Don't know anything about the Mauser line ... I thought broom sticks had longer barrels, but this one has a short (5-6") barrel, and had a vertical magazine receptacle with no magaizine ...
The only stripper clips I have ever seen were used in the Garand M1 and M1 Carbine, were fed thorugh the top with a closed bottom on the clip.
This Mauser had a wooden holster that became a stock, and open clip bottom with rounded front and rear edges of the magazine receptacle.
I would again like to stress that I know very little about Mauser pistols, and had questions based on my very small knowledge of Mauser magazines, stripper clips et al.
And I don't wish give out bad info just because I had very little knowledge of the weapon .... and I could not see the armorer making the same mistake over and over
