Hello fellows ( or hola senores)! I'mtrying to find some info on a shotgun my dad gave me. He tells me he has no idea where it came from and doesn't remember how he got it.
Anyway, it says "Procomsa Principe-Bilbao" on the top of the barrel. I assume this means it was made somewhere in the Basque region of Spain. After that, some proof markings then "850 kg". The underside of the barrel (actually the breech) has "410-76" in an oval of sorts, then "K.L. 54471"
There is also "30." stamped on the barrel at the hinge assembly. The same info stamped on the underside of the barrel is stamped on the receiver.
My impression of this gun is that it is a cheaply made firearm. The hammer is difficult to pull back as well as the trigger having an extremely heavy pull. The barrel is 27 inches long with a sling attachment soldered to the barrel about 10 3/4" from the muzzle. The action is opened by a side lever. The wood appears to be cheaply finished.
Sorry no pics...can't find my camera. Any help would be greatly appreciated.
