Maybe somebody will find this interesting.
Even though the present situation is nothing like England in 1939-40, somebody claimed that they were so short of hunting rifles for civilians that the UK govt. requested the US govt. to send over lots of extra rifles and ammo, to deter a German invasion.
That was just a tiny drop in the bucket compared to weapons etc they received under the Lend Lease Act, while we stuck our heads in the sand
(other than our volunteers via Canada for the RAF, and Flying Tigers etc).
We sent a fair number of rifles, donated by private citizens, but I don't know where to find the info.
