Re: 1972 MFG Gypsy
If your boat had the metal emblems, there should be rivit holes where they were attached. If the boat had plastic emblems, they were stick on (I think) and may just leave a shaddow.
Stickers are just not available to my knowledge.
The emblems in that link were used up through the early to mid 70's. Some had the MFG flat letters, some had the MFG with a raised outline. I can do the flat letter style.
The more you work on the boat, the more you realize why it lasted so long. The hulls are very tough, and when wood was used, it took a long time to get wet and rot.
