The original Charlie G's were a strange paint. It was a baked on finish and to call it gloss was over selling it. To call it satin was under selling it. And it definately wasn't matt. It was almost but not quite gloss. Eventually they were painted in the same paint as the 81mm mortar base plates. Not IRR, not gloss, not matt, not satin ......, a sort of glossy satin or satiny gloss!!!!!
The No32/L1A1 scope boxes were definately gloss deep bronze green as were the 3" and 2" mortars.
I wonder if Carl Gustav werk in Swedenwould look kindly on a request for some obsolete parts especially on headed ABFmuseum paperwork.
