Pre-WW1 Russian 37mm case

Got me on this one--
We had better ask for help from a higher power - they know who they be --
How does it compare the the U.S. 1 Pdr. H case, is it several mm longer and is the base the same or does the base match instead the 1891 Winchester Hotchkiss if you have one. I'm kind of thinking a Nordenfelt round, but with the screw in primer it certainly is odd. And it is definately 37mm not 42mm etc. If it's 42mm it is a Nordenfelt.

I can't remember how it compares to either of these two - I've sold mine, but I'm sure it was different to both. It is 37mm. Trevor

The markings on the case 0.622 & 12 would give a case length of approx 37x190R
Not sure that helps.

The case length is 139mm and I don't think it's been cut down as the three crimp marks are the 'correct' length from the mouth when compared to many 1pr pom-pom heads. The mystery goes on!

The Base
going by the measurement given is the same as the Hotchkiss 37x120 or 37x100 cases and also the British (V.S.&M.) 1 1/4 Pr and 1 1/2 Pr. cases. What this implies is that it is used in a design similar to a product from these companies as it is a common to all breech size.(or with a barrel change you can upgrade the existing gun) But to ensure a particular supplier the case is a different length, a common trick of the time. What ever used this is not the regular combat types or we would have seen this case more often. I'm thinking possible Navel subcaliber use, or a trial piece. If loaded with a regular 37mm projectile this would have given a superior performance to most everthing except maybe the French 37x202 Tube Cannon round also a subcaliber type originally.
