Sheri,
This is probably too late for you ….. and you’ve probably found Alfred’s records on FMP by now.
Nevertheless, a couple of points:
His “regiment” was the Corps of Armourer Sergeants ….. whose Depot was the Royal Small Arms (Repairing) Factory, Millbank.
Once qualified, Armourer Sergeants were posted ….. more correctly: attached … to Infantry (and Cavalry) Regiments. They wore the uniform of the Regiments. With the exception of the Armourer trade badge of the Hammer and Pincers / Tongs worn above the chevrons on the right arm, they were indistinguishable from members of the Regiment proper.
Alfred was attached to three Regiments:
1863 – 1870 Royal Canadian Rifles
1872 – 1878 5th Regiment of Foot, 2nd Battalion
1879 – 1880 38th Regiment of Foot
At all other times, he was posted back to the Millbank Depot.
Incidentally, a Samuel Sutton, Gunsmith, b. 1836 (Parish of St. Pauls … near Birmingham … County of Warwick) also enlisted in the Corps of Armourers in 1861.
Regards,
