Soviets have RMN-50, Japan have Arisaka Mortar, I suggested Sturmkampfgewehr and Granatkarabiner for germany, also the lanciabombe from Italy (and seems Euthy liked it), now I suggest this thing for Allieds, directly from official museum
A newly designed 2½ inch discharger cup was produced for the No.4 rifle," is quick search, that gives no info on the armament.
British used 2in (51mm) mortar at the time so mortar shell doesnt seem compatible, which is the point here, both Arisaka and RNM fire mortar shells, NOT grenades.
in the museum page you have the info, I know they where mostly grenades, but I think one was incendiary, the only thing we could use then, it’s the american modification who throw rifles, that’s why I speak about add it my man
I think this grenade launcher should use the No. 68 AT grenade, because it’s filling weight is 156 grams, which is more powerful than the Type 89 50 mm HE(150 grams).A hand mortar with 52 mm of armor penetration would be more valuable as a BP weapon.
you only need think, its not only a mortar, but it can be other ammo, in the museum page you have a list of the ammo it used, so it could be a cool weapon
acording to the one who was sold in auction house probably around 1944, from museum, if you check and zoom it you can see the 1944 mark, so yes, we are in WW2 period
Yeah, according to the serial number (BU12685) it was manufactured in the Royal Ordenance Factory (1) Malby, the BU batch correspond to the period when 450,000 - 460,000 were made already, 2685 is the exact number this weapon was assigned. Late production rifle, 1944 indeed.
