Does the right side of the frame say "Made In U.S.A." in one simple line or is there a longer 4 line address there? The one line guns have some added collect ability because they are the earlier rarer version of the post war k22.
Next job is post some pics.
Let me add that your gun is pretty early in the post war production and is a pretty collectable item. To keep the value, don't make any haphazard modifications, don't loose the stocks (if they are original) and don't reblue. Often the stocks are numbered to the gun with pencil on the underside of the right side grip.
Remember, post pics.
