I have a 1938 Colt Officer .22 with 6" barrel. Its in good shape. I want a Walther P22 or a .17 rifle. Open to trades or sales. I have been told my pistol is worth $600-700. Dont really know alot about the pistol but I know I want one of the above guns. Its been in the family for a long time so I dont have papers. Thanks.
