Enfield Rifle Oilers, MKII and MKIV.
Couple of oilers i just found in a box and luck enough one is a MKII which would date it at being a Victorian example. The MKII has an armourers stamp to the top, looks like,N over 90, the bottom having a ''WD broad arrow'' stamp and inspection mark , crown over B5. The MKIV at the bottom is stamped with a broad arrow and an inspection stamp , crown over AH13.
