That's a beaut, I have it's cousin UF 55 A14963, identical finish. Mine has a C.A.I. import stamp right side barrel just aft of the muzzle. Your beech wood stock and magazine may have matching serial numbers as well. Looks like yours has a perfect wood repair right side stock just forward of the bolt handle. In the Southwest you would expect to pay $300-$500 at a gun show on a good day. Cheers, Don
