Any thoughts what it is and who made it?

The case dimensions match the 7mm Canne Ball case (aka 7x13R Walking Stick) but other French 7mm short cases are very similar to this (7mm Dumonthier 7mm Revolver).

Also, I have not seen an IP case for this caliber without a hs - is an image of the hs possible please ?

Being IP it is most likely of Gevelot, Gaupillat or SFM manufacture.

Thanks for the reply. Here’s the base.

Were these IP’s typically sold as NPE?


Paul, I doubt that these were offered as NPE - I can’t recall seeing any in catalogs. Some of the shot or propellant charges (blanks) may have been, as they could have different (powder/shot) loadings.

I can’t tell from the images whether yours had the bullet removed ?

WBD thanks again for your replys.
I don’t think it was ever loaded. The case doesn’t show any signs of a bullet crimp or any other indication it had been loaded.
