I understand that this corps was founded in 1858 and subsumed into the Army Ordnance Corps in the 1890's. I am having some difficulty in trying to find information and whether there was any book published on them. My visits to TNA have not produced any results at all. So if anyone is able to help, I would be extremely grateful.
There is no book as yet on the Corps of Armourer Sergeants, but over the last two years I have been communicating with an online friend in Australia who hopes to write one. I have been helping him with research and we have already learned a lot about this small, but important corps. As a start point you should understand that they were always during their existence closely associated with the government contracted arms works, each of which became also their regimental depot and HQ. At first this was in the factory within the Tower of London, it then moved to a larger factory nearby and then again to a much larger works at Enfield (in Middlesex but later Greater London) which grew out of the increased demand from the Crimean war. Finally, later in Victoria's reign it moved to Birmingham (to Sparkbrook and another location), until the armourers lost their own corps and became a part of the Army Ordnance Corps and the tie with factories became severed. It seems that the only officer to be badged to the Corps of Armourer Sergeants was the quartermaster, and all other officers were seconded from other parts of the Army, especially the artillery, but also including infantry and cavalry officers in various senior 'staff' roles as inspectors and intermediaries between the factories and the war office. The armourers themselves were trained at the factories and certificated as 'qualified' by them too.
You can communicate with my friend at the Victorian Wars Forum where he posts as 'Peter' and I post as 'Frogsmile'.
