Not this piece of junk, is it?
That was discussed on another board at this thread;
Three very dodgey-looking 'rare' firearms up for auction.
As I wrote over there;
An Indian wire-wrap is chopped, and has an unusual grenade cup. Claimed to be a 'No4 discharger cup', it does not look like the actual No4 discharger cup, which was introduced in 1942, designated as Discharger No.3 MkI. This cup was made for the No4 rifle, and was attached to the rifle with "a turning collar which locks behind the lugs on the rifle, the same lugs that also fix the bayonet" (Skennerton, The Lee-Enfield, p415). So, the 'cup' featured cannot be the cup in Skennerton, as they fit different rifles. The one in the auction does not have the base that actual Discharger N0.3 MkIs did, and it is fitted to the wrong rifle, the wrong way.
Grenade launching rifles were bound with wire as the stocks sometimes cracked or shattered due to the increased forces on the rifle during grenade firing. I can hardly see an Indian GF rifle being chopped back to the main band, as that would make the comparative pressures even higher.
