I have a hard time figuring out what 20mm stuff is. These two came from Berk Lewis collection and I believe are 20 x 105mm Belted, short Rheinmetall-Solothurn. Can someone tell me who made them, (and for whom if for export), the type of load, and if they contain any HE.
Thanks in advance for any help.
