Hi I managed to buy a mint condition SMG double magazine pouch, for £7.
It is completly unmarked, no wear marks at all, apart from the still visible chalk manufacturing marks, the store refs are clearly visible:
"M.W.&S. LTD. 1974 (arrow)
CN 8465-99-136-1905".
will post a piccy asap.
(I bought it from an antiques shop just off the highstreet, in Sheringham, Norfolk.
loads of other kit there quite alot from the 1940's period.
