Thanks for the help. That was the site I had originally looked at from a previous thread. I looked through it again and still think it's from the 40's. Looks like the D-23 to me. It was one of their most popular models so it makes sense. Unfortunately not too rare so maybe i'll get around $30+shipping for it. Still not a bad buy or $2, so i"m happy with it. And I got to learn a lot about Disston saws which is good for future picks. I normally don't spend much time in garages at estate sales but there wasn't much else worthwhile at this one. To someone that knows tools, there probably was much more to be found that I missed. Tools is one area that I don't know much. Seems like there is good money to be made in that category though. Some of those Disston saws can go for $150+.
