I may not be fancy but the best I have been able to figure out it was make in the 50s. Its all reveted. When I got it it was nothing but a tin shell. I had to try and remember what the wood in a boat like this was like from when I was a kid about 12. So has anybody got and idea as to what it is and a year. It's 10 1/2 feet long.
