Unknown Mortar Round

[ordnance]

Saw this one in an auction and don't recognize it. Can anyone help? Just the two photos with no size details, unfortunately. Pretty distinctive with the heavy obturator bumps and heavy fuze.

I get a British 3 inch buzz from it.

Strange, the fuze looks like a modified german ww2 LWMZdr2 (safety with 2 pins)

As I wrote previously, the fuze is very strange (looks like ww1 german Lwmzdr2 modified on top : fake ?)

For the shell, for sure it's not a fake and probably an experimental round as I found in US-SUBS archives (Aberdeen) a projectile with same design with a winchester cartridge.
Interesting.
