From Wikipedia:
The London Armoury Company (LAC) produced their own barrels for firearms like the Kerr revolver and Pattern 1853 Enfield rifle in the early 1860s, often marked "LAC" or with specific inspector marks. While the firm was known for assembling firearms, key components, including specialized barrels, were often manufactured in-house or sourced from specialized Birmingham and London barrel makers during that period.
-- In-House Production: Many LAC barrels for their 1860s-era revolvers and rifles were produced in-house under the direction of superintendent James Kerr.
-- Barrel Makers & Marks: Some, or part, of their barrel supplies may have come from known London gun trade barrel makers, such as Charles Lancaster.
-- Proof Marks: LAC barrels typically carry London proof marks rather than Birmingham proof marks.
- Key Figures: James Kerr (foreman/superintendent) was central to the development of the company's rifling, including the .451 caliber Kerr rifle (circa 1860-1861).
Was Lancaster making his own barrels in the 1850's? Were there "London barrel makers" in the 1850'? My understanding is, "No there weren't."
