The LeMat revolver was manufactured from 1856 to 1865, with approximately 2,900 being produced. The first models were manufactured by John Krider of Philadelphia, with the second model (the first overseas model) being produced by Charles Frederic Girard and Son of Paris. Quality concerns prompted LeMat to consider production at the Birmingham Small Arms Company in Birmingham, England, but production was never mounted there. LeMat revolvers from France were shipped to the Confederate States forces via the United Kingdom, and all firearms landed in the UK were (and still are) required to be proofed. The LeMats which found their way through the Union blockade were stamped with British proof marks from the Birmingham Proof House, leading to the misapprehension that the pistols were actually manufactured in the UK. A handful are known to have been made illegitimately in the UK by an unknown manufacturer, believed to be the London Armoury Company, but only two examples survive to the present day and it is doubtful any of the English-made LeMats ever saw service during the U.S. Civil War.
