Good news, Rob, is that is not a #7, but likely a D23, which was a little bit more expensive saw than the #7. If your identifying it as a number 7 was based on a number stamped into the blade, then it is likely that the saw started off with 7 tpi.

I think Jerry is right, it looks like a pre-1928 D23. I have the same era D23 and it is one of my most comfortable saws to grasp. They really made great handles back then. I have several saws after 1928 and they do not match up in handle comfort.
Thanks Bill and Jerry. I was up the other night till late trying to get a handle on what they claimed. Funny i finally came to the same conclusion that its is D23 but i will wait and see what arrives. I hope i aint been duped with something else here.
