Unknown round


#1

Here is a steel case shell.
look at the rim and the groove;
Who has such a round in his collection ?
And who has some idea of what is it ?
thanks
Jean-Pierre


#2

Headstamp (if present) and precise mesurements?


#3

Does the shell use a primer or a percussion cap? What are its dimensions? It resembles a .41 Roper, except that the ‘belted’ portion above the groove is not as wide as on the typical Roper.


#4

No hstp
It is about 40 mm diameter


#5

It uses a primer.
It is 40 mm in diameter


#6

If the case is about 240mm long it could be a 40mm Swiss Hispano-Suiza for AA gun.


#7

case length : 183 mm
Rim diameter : 47.20
Neck diameter : 37.20
Base diameter : 43.25

Have you a picture of the Hispano suiza ?

Thanks
JP

This fellow from my collection looks like it might be the little brother of yours. This is so far unidentified.
It is an unheadstamped loaded round with a deep seated cloth wrapped projectile and percussion primer.

What are the dimensions ?

I don’t have this any longer so can’t measure it for you. You can see by the ruler that it is a lot smaller than yours.


#13

the rim looks different.Do you remember to who you sold it ?

#14

So nobody has such a round like that (or other dimension) in his collection ?

JP–Hard to say if “nobody” has one based on the response on this Forum. Only about 10% of IAA members participate, not to mention world-wide collectors. One area where very few of the major collectors are online is shot shells. You are about the only only one. I am not sure why that is as there are several U.S. Experts in the field of shot shells.

Could this be a punt gun case? I would like to see the base.
