Just joined yesterday but refered to stovebolt to answer some questions. I just purchased a 1950 3100 in march. Its in pretty good shape buts needs a lot of TLC. Has a newer 235 w/3 on the tree. Engine s/n is T701A. I think it maybe from 1957 but not sure. Be forewarned that I have a lot of questions and will greatly appreciate any advise and help.
