purse gun?

 

[peckerwood]

I know that it is based on a Lefauchaux pinfire...but what in heck is the calibre/cartridge?

I to this day have never seen that type of cartridge before...have you or anyone else ever seen anything like that bullet?

The cartridge is a 4mm. The cartridge was used in subcaliber adapters, indoor "parlour" target shooting guns.

Any specific idea as to what the cartridge is called...is it a rimfire, even though it doesnt actually have a notable rim; just a rear bulge?

It really is an odd looking cartridge. I noticed that Sellier and Bellot still makes Flobert 6mm. Do you think they or someone else still produces these cartridges.

I am still at odds with it's wierdness

4mm Zimmer Scheutzen.

 

[peckerwood]

You seem to have your head firmly wrapped around this one...are there any other calibres in this strange cartridge ignition design?

It is an inside primed centre fire ctg developed in the 20s by RWS for short range indoor target practice. Usually used with a barrel insert for temporarily converting 9mm,38 etc. Official name "4mm Ubungsmunition M20".
