Stamped markings identification.
 

Any help would be appreciated. I also can't find a serial number on this gun.
As far as, the "Cochise" stamping, it looks like it was stamped after all of the other markings. It doesn't look near as old.
Thank you, Chris

That is not a Parker Brothers gun. Cant help with anything else.

Well dang. Thank you for the reply.
I'll get more pics later. It is stamped parker on the side, but i don't have those pics right now.

It will only be marked Parker not Parker Bros, Its not made in the USA as what this group is mostly about . Im not up on my Proof marking but that is some on the frame water table you show research them and others you find on the gun and you will know what you may have , Stamping looks to indicate it was owned by a sheriffs office in Arizona ?

It is a Belgian “knockoff”. As they say.
