I put in order the archives and have found old record about sale of the Mauser Broomhandle stripper clips. These clips have seemed to me unusual. Here that the seller writes:
[color=#0000FF]Extremely rare stripper clips for Bromhandle Mauser Mod.C96 of the German imperial navy! Navy proof with imperial crown and M for Marine (navy) Stripper clip and feather nickel-plated. Clip has corrosion by use in the navy and seawater. Auction contains three clips, see picture. Rarity for the WWI navy and Mauser collector! [/color]
I saw brands from the manufacturer, but I never saw brands of the customer. Somebody saw such clips? What can you tell about these clips?
