I have a fabrique national 9mm browning paten disposed, what is on it that I can't get info on is on the right side it says " policia prov.bs. Aires 61... It has many strange maker marks and proof marks.. The serial# 03236" people have told me it has to have a prefix, or letter code, but this does not.. Also just in front of the rear sight is a crest.. Shield like engraving.. There's also a crest on the chamber just above the serial no# please feel free to email me direct, tattooed@live.com. Anyone that could help me with the history, value, or any info on this side arm is greatly apreciated....I have to say I truely love this weapon!
