9mm Star BM

Just a guess, but since Spanish tends to initial the opposite from English. This may stand for "Nitro Proof" or "Prueba Nitro"

Another wild guess would be "Policia Nacional" or "National Police"

Thanks for the replies!

Could very well be (the 4-digit number); the 7-digit number may not have been convenient for CAI to fill in their forms...

Policia Nationale was my first guess, and also the guess of a member on Gunboards/Spanish Pistols...

But no one has identified the cartouche...I don't really buy the "proof" guess for the cartouche (not yet, anyway), as why put a proof on a part of the pistol that is not stressed??? (And is easily separable from the barrel/frame). And the barrel/chamber already has a proof (looks like a flaming bomb)...
