Have you seen the old ads/flyers for stainless steel/galvanized steel boats. I googled it and an ton of vintage ads came up. I bet you can find it there
All of the Starcrafts I have seen from the 40s-50’s have the star logo on the two corners on the rear of the boat. I will post a pic of mine. I am almost certain mine is from the 1940’s. It had a metal covering over the bow but it was so damaged we replaced it with wood
