The deck looks like an early Old Town. Beyond that, it doesn't look like most old Towns. The keelson is smaller than usual; the half ribs are somewhat crude; The ribs look untapered and the from the tops, the edges appear unbeveled. The transom braces don't look correct, but they could have been changed. The thwart brace and other metal braces were probably not from the factory. I have seen other square sterns that look as though they possibly could be Old Towns, but also had many unusual characteristics. If you can use some chemical stripper on the stem to determine the number, you'll know for sure. I would not say definitely whether it is or not.
