Here is a selection of factory drawings/blueprints for how Eley Bros made pinfire cartridges. These blueprints date to the early 1900s.

First up is the 5mm pinfire cartridge drawing. There is a lot going on here! It lists the dimensions for the bullet, the pin, the percussion cap and the case. They also give all of the dimensions in imperial units though these cartridges were always sold by their metric designation, “5mm.”

The bullet is described of being made of 98% lead and 2% antimony. The antimony was an additive used to harden the alloy. It was a hollow bullet with an overall diameter of .207 inches, or 5.258 millimeters. It had an overall height of .300 inches or 7.62 millimeters. The bullet weight is 18 grains and the powder charge is listed as “about 1.5 grains.”

This matches up closely with examples in my collection which have a bullet weight of 18.0 grains and a powder charge of 2 grains. The overall weight is 35.2 grains.

The brass case is listed to have a mixture of 70% copper and 30% zinc to make up the alloy they used. The case had an overall length of .450 inches or 11.43 millimeters. They give the exact specifications of where to put the hole for the brass pin and even what angle the pin should be placed in the cartridge to ensure the hammers get the best hit.

There have been many articles written about Jean Samuel Pauly and his contribution to the history of firearms development. One excellent source recently looks in detail at the patents by Pauly, Roux, Picherau and Lefaucheux. You can read about it here:

Priestel dives deep into the modifications by Pauly and the successors to Pauly’s company, but there are a few other improvements to the Pauly system by other prominent gunmakers of the day that are not addressed in this publication. A couple of these were mentioned in a French gun magazine’s article in the 1970s, but other than the brief mention there, there is nothing I could find published that goes into detail on the following improvements to the Pauly gun and cartridges.

So I gathered the patents, transcribed them and will detail the improvements here!

Jacques-Joseph Plomdeur | 1825-03-31

Jacques-Joseph Plomdeur was a well known gunmaker who had a business at 25 rue des Fossés-Montmartre and later at 5 bis, rue du Faubourg-Poissonnière. He was best known for his improvements to primers and percussion caps which he held a few patents on. In the 1830s he took out many advertisements for his improvements to guns and primers such as the following:

On 31 Mar 1825, Plomdeur took out a French patent for 5 years for an improvement on Pauly guns.

There are two main areas that he addresses. First is how the hammer is connected to the plate, passing all the way through, which allowed for considerable fouling throughout the inside.

James Erskine, a gunmaker and inventor from Newton Stewart, Scotland had a prolific career inventing and patenting many improvements to guns and cartridge loading machines. His patented cartridge filler was universally accepted and used by all of the great British gunmakers of the day!

Erskine was born on September 12, 1812, in Penninghame, Wigtownshire, Scotland, the son of Mary Watson and Thomas Erskine. He married Elizabeth Sinclair on December 4, 1854, in his hometown. They had eight children over 21 years. He died on November 20, 1891, in Newton Stewart, Wigtownshire, Scotland, having lived a long life of 79 years.

During most of those 79 years Erskine was active learning and then working in the gun trade. The IGC Historical Database indicates that Erskine began his apprenticeship at 14 years old, working as a gun finisher for Williams & Powell, or their predecessor, Edward Patrick in Liverpool.

Sometime after 1841 and before the 1851 Scotland Census, Erskine moved to Newton Stewart and began working for himself as a gun maker.

He displayed two guns at the 1851 Great Exhibition and was awarded a bronze metal.

On July 20, 1859 he delivered the following provisional specification to the British patent office for an update to the Lefaucheux-style pinfire shotgun:

August G. Genez was a French Gunsmith that began working in the gun-making industry at 13 years old in France. He died on June 17, 1897 and over the course of his career he had many successful ventures as well as challenging tragedies.

This article will take a look at A. G. Genez, the gunsmith in New York, New York, and follow his 50-year career in the gun industry. We will also take a look at his successors of his gun shop, Vincent Bissig and John P. Dannefelser.

When August Genez was 21 years old he immigrated to the United States from a port in Le Havre, France on a ship named Charles Thompson and arrived in New York, New York on April 10, 1854. The ship log of his emigration record states he was from Germany but his naturalization record, son’s wedding record, various ads of his, son’s various census records all state his birthplace was France.

The Genez name first shows up in the 1856/1857 issue of Trow’s New York City Directory where Genez August is listed as a gunsmith at 221 William. The same year the Wilson’s business directory of New-York City list him under the Gunsmiths section with his business at 221 William.

The Ironmonger & Metal Trades Advertiser was the first trade newspaper. It was first published as Morgan’s Monthly Circular & Metal Trades Advertiser on May 31, 1859 and soon changed its name to The Ironmonger & Metal Trades Advertiser.

It began as a monthly journal and by 1878 it was switched to being published weekly, every Saturday. They also published the yearly volumes capturing the 52 weekly issues in 2-4 large volumes per year. I recently acquired a set of these yearly volumes that cover the years of 1879 – 1903.

There is a wealth of information in these related to the hardware and metal trade across the United Kingdom. They had weekly stock performance, tabulated results on UK exports to the US, foreign news and intelligence, reviews of agricultural shows and other exhibitions, articles about guns and ammunition, listing of patents and trademarks applied for, information on liquidations and bankruptcies and advertisements; many many advertisements.

We have examined this cartridge previously in our exploration of the relationship of pinfire cartridges and The United States. You can read about it here:

The August, 31 1861 issue of The Scientific American reviewed this new cartridge and gun made by Casper D. Schubarth in detail. I found an original copy and transcribed it here to preserve for the future.

The story of Coirier à Clermont is a interweaved tale of partnerships and encounters that begins in 1848.

In 1848 a Frenchman named Francis Marquis founded a company that made carbines for cavalry. In French this is the term, harquebusier. He was known for making high quality guns and displayed some of his work at the Exposition Universelle of 1855 in Paris, the 1862 Great London Exposition and the 1867 Paris Universal Exposition.

Shortly after the London Exposition, La Chasse Illustrée, an illustrated journal dedicated to all things hunting, featured an article about some of the high grade guns presented at the exposition. They described Marquis’s gun as “remarkable” and “a real masterpiece.”

South American Pinfire Cartridges are pretty uncommon! Pinfire guns had a relatively significant use in South American countries such as Argentina and Uruguay as many were imported for many decades. The large 15mm pinfire guns were especially popular by farmers as a large side arm to protect from wild animals.

This is a high-end 15mm pistol that came out of Uruguay. It was made by the luxury gun manufacturer, P. Boissy somewhere around the late 1850s to 1860s. He manufactured his guns in Saint-Étienne, France and even won an award at the Exposition Universelle of 1855 in Paris for his “pistolets de luxe.”

Charles Millichamp of Presteign, Radnorshire, Wales was a watchmaker who owned a fishing tackle shop. Over a few decades he made significant use of advertising to inform people about his new endeavors. One of his earliest ads was for his business, County Sporting Tackle House, where he advertised his custom trout & grayling flies as well as all kinds of fishing tackle that he sold.

In 1888 Millichamp worked with William Maund who was a landowner that lives about 6 miles away in the village of Shobdon, Herefordshire, England to invent a new mechanical scarecrow in the form of a self-acting field clock gun. They patented this new invention on May 3, 1888. You can read more about the patent and see high quality images of my example of this gun in my earlier article.

Maund and Millichamp very quickly began getting press and reviews written about their invention in various publications. You will notice that sometimes the review mentions both inventors and other times it mentions only one or the other.
