4) By what method where any Enfield Enforcer rifles disposed of? Destroyed, sold to the civilian market etc.) 5) What were the serial numbers of any Enfield Enforcer rifles that were destroyed? 6) I would be particularly interested in rifle serial number 415 which was issued to you 3/1/1974 as I know that some of its parts are in Canada. Enfield Enforcer RSAF SN# 391 7.62 Nato Bolt Action Target Rifle & Original Pecar Scope. At Enfield Lock. Model: Enforcer. (back from proof) This unusual Enfield Enforcer action based rifle has a pupose built.22 Enfield barrel and bolt fitted, with military marks on the barrel and action and a new current Birmingham proof. The OP does in fact have a No4 rifle. It has been scrubbed and the receiver has C-13 stamped on it and pretty much nothing else. The bolt and magazine have the Y3. serial numbers. Those are BSA serial numbers. I found an excerpt from Ian Skennerton specifically speaking about Singer Manufactured items. We cannot say for certain it is a year, nor can we say for certain much of anything else about that number. All we can go by is the serial number. But here is the thing, that number on that No 4 is stamped in an area where some manufacturers stamped the year it was made. That is a red flag to me.
Up until 1940, BSA made normal high-quality No1 MkIII* on limited military contracts, marked with the usual Crown and BSA&Co, as well as identical rifles just marked 'BSA&Co' for commercial sale and export.
With the invasion scare, the Ministry of Supply ordered BSA to make rifles out of whatever parts it could get together. Hence the rifles were made of mixtures of commercial and military parts, mixed walnut and beech wood (or all-beech), later on No4 butts and firing pin/cocking pieces. A second wave of production in 1945 even used recycled and re-dated receivers.

About the same time the emergency rifle production was started, BSA was ordered to disperse its many Birmingham factories away from the bomb-target central area, and also to increase war production by diluting experienced staff with war staff. BSA was a huge engineering group, and this 'Dispersal' programme led to 70 seperate factories being set up, moved and/or expanded. Rifle production involved several of these factories (both No1s and No4s), and this type of 'all available parts' No1 has become known as a 'Dispersal rifle'. Technically, even the No4s were Dispersals, as well as motorbikes, bicycles, aircraft parts, machine guns and heavy weaponry...
BSA marked these rifles with just the first 'B' of BSA&Co. Presumably this was to dissociate the company from these slightly less-than top quality peacetime rifles!
