Here are some pics of carbine accessories, some rare, some not so rare.
Top is a standard GI valaise, second from the top is the poorly designed M1 'holster' (the thing actually has a belt loop on the other side!) and bottom is an M1A1 jump bag. I tried on the holster once, it hangs pretty much to my ankle and makes even walking difficult. My splits in IPSC would suffer I suspect!
This is an "invasion bag", the green plastic sacks that troops who were to land on the beach were issued to wrap their rifle/SMG in to keep it dry. Has 1944 and a part number stamped on the other side.
This is my M1/2 all dressed up. The round thing above the mag is the mount for the grenade sight below, the white thing is plastic impregnated paper with instructions on how to use it and suggested range settings. All comes in the little pouch below. The thing above the barrel is a muzzle cover, designed to fit the M1 Garand, M1 Carbine or other light arms.
Anyone else got stuff to show and tell?
