The guns produced on the Confederacy's London Armoury contract were of the highest quality. Interestingly, just before the outbreak of the war, the company had taken delivery of the latest stock making equipment from the Ames Manufacturing Company in Massachusetts. The rest of their equipment was equally up to date. Parts were gauged with English government gauges and fit up to the best military standards. Once inspected, probably by British government inspectors on Confederate contract, they were loaded on fast blockade runners, many of which were also made in England, for the trip across "the pond". Surprisingly, most arrived in southern ports. The life expectancy of the average blockade runner was about six trips before being captured or sunk.

The southern L.A.Co. Enfield is not only well made, but one of the best finished arms to see service in the Civil War. Stocks were either a light colored walnut or beech, stained reddish brown and oil finished, or first quality Italian Walnut. Buttplates, trigger assemblies and nose caps were polished brass. Locks and hammers were color casehardened while barrels and barrel bands were "blackened" to a beautiful deep blue. Unfortunately, it was very common for soldiers polish the barrels bright. Unlike many Enfield contractors, London Armoury plainly marked their locks "L. A. Co.", not the bogus "TOWER".

The war was not kind to the London Armoury Company. Most of the pay on their Confederate contracts was in cotton bonds, deliverable at some future date. These bonds were widely traded on European commodities markets, and were generally as good as gold, up until early 1865. With the downfall of the Confederacy, they became worthless. London Armoury held millions of dollars of them. It was more than the company could absorb, and the doors closed on the first private contractor in England to build parts interchangeable products.
