I have one which appears to be just like your pistol.....I never really knew much about these pistols until I researched them...
Mine is a Model 922 also....same grips.....9 shot / 22 cal......Mine is a what has been called a Full Pull Pin (?)...The cylinder Does Not tilt out to unload / load.....On Mine....You push the pin release and pull the full pin out ...the entire cylinder then comes out to unload and reload...... " Sort of a Rube Goldberg Designer Series ".....but unique pistol...and most people have said that these pistols are very accurate (?)......
According to the limited website(s) I found....Mine has a serial number M35XXX....which states that it is a 1952 model...You can go on the Model 922 website and check your serial # and it will tell you what year it is.....
Price ??? According to websites.....I have seen prices up to $200.00 + /-.......Mine has the original heavy leather holster with it...
As you know.....Something is only worth what someone is willing to pay for it !!!!
But this pistol belong to my Grandfather......So.....
