Good Evening!

I generally prefer Japanese saws, however over the last few months I've
purchased a few vintage Disston handsaws at garage sales and antique shops
and I don't think I've spent more than $5.00 on any of these saws. Upon
further inspection, I believe three of these saws could be excellent
workers. But before I spend any time or effort cleaning and sharpening
these, I wanted to get the sage opinions of you Galoots who have much more
experience than me.

The first saw I believe to be a Disston D8 rip saw from 1888-1896, 23" in
length, 4 TPI.

The next saw I believe to be a D-23 crosscut  from 1940-1947, 26" length,
10 TPI.

The final saw I have no idea. I believe it's a crosscut from 1940-1947, 20"
length, 9 TIP.

But, I could be totally wrong. Please take a look and let me know what you
think. I appreciate the help and feedback.

Thanks,
