I have a model HD Hi Standard Military semi-auto .22 cal pistol with 4 1/2" barrel made around 1945. Serial # 145XXX. It is in excellent condition, no visible scratches. Has one small place at end of muzzle on left side where bluing has rubbed off. I'm assuming due to fact it has been holstered. I am trying to find the fair market value for this gun, but not having much success online. Does anyone know the value or where I can look it up online? Gunbroker.com does not have it that I can see. Thanks in advance for any advice. Steve
