I know nothing about these guns, but I did inherit these and a few others from a great uncle who passed and apparently his father was a tail gunner in Wellingtons primarily based over North Africa. These were with quite a few WW2 relics. These seem too new to be wartime,

Another is a SA58 Para FN with 11" barrel and factory scope. Looks really cool but definitely newer.
