Know anything about this pistol?

I've had this pistol for years and don't know anything about it. What size ammo? What year was it made? Does it has any value? Here's what I do know: the left side of the pistol says the following "FABRIQUE NATIONALE D'ARMES DE GUERRE HERSTAL BELCIQUE" and below that it says "BROWNING'S PATENT DEPOSE" and below that are some weird symbols for example a star with the letter M below it, and what appears to be a stick figure man with a line under it and the the letters PV below that. The grip has the letters NF on it. The finish is blued.

hello,,you have a model 1922 pistol made in belgium somewhere between 1923-1959,,caliber should be 7.65(32acp) or 9mm short(380acp),,very well made pistol and during ww2 these were used by the germans and will have german markings ,,many countries used these pistols and value for yours would be proably in the 275-350 range,,mabey alittle more with more research ..and depending on if it's a contract pistol.. and which caliber it is ..thats something to get ya started with..and a ballpark figure..
