Kimel Industries .32 Cal Revolver - Anyone familiar?

[allingeneral]

I've had a question posed to me about a Kimel Industries .32 caliber revolver - Model 5000. The query is "What ammo should I use?". As far as I can tell, it should shoot .32 Long or .32 Short - but there are a couple of different versions.. .32 S&W Long and .32 Colt Long - .32 S&W Short and .32 Colt Short.

Can someone help to clue me in on the differences between these rounds and possibly help answer the question about the Kimel 5000?
