I have an older semi auto firearm that I am looking for some information on. It has "FABRIQUE NATIONALE DARMES de GUERRE HERSTAL BELGIQUE" on the left side of the firearm. On the top it has a "Queens Crown" on top of a "W". The left side also has what looks like a small "lion" on top of a "line". Under the "line" is the initials "PV" which is on top of a "star" which is on top of a "N". On the left side is also the words ""BROWNINGS PATENT DEPOSE". It has a 4 diget serial number starting with 5. On the left side trigger guard is the initials "FN" which are inside a "Oval". The magazine has some markings with "9m/m" under them. The magazine has a 5 diget serial number on it that does not match the firearm. It has some wear on the end of the barrel and all serial numbers match other then the magazine. I am interested in the year, condition, military/non military and overall approximate value of this firearm.
