I have a shooter K-38 Combat Masterpiece, same year and month. Didn't realize it until I recorded information for records.
My prize is a same year only K-22 Masterpiece Pre Model 17, 99%+ with correct box and grips numbered, and all the trimmings. My Mother gave me a little money and told me to buy something nice for myself. The rest went to paying bills. She left us a year or two later, making it even more important to me.
