Benson, my error. I can confirm 15 length. Using graphite rub I get 32838 15. It was retrieved from northern Minnesota. It was worked on once and glassed-over pre-epoxy. Bow stem rotted-out, base of stern stem with serial number barely hanging on. A 15 50 confirmation will help me research original specs/measurements for restoration. Thanks, I appreciate your help.
