I picked up a very nice and clean Disston D8 a couple of days ago. It may be in the best shape of any old saw I have acquired. The toothline was dead flat, set was good, teeth very sharp. I am not sure if it was ever used much at all.
The Disstonian site shows this about the medallion. I call it a "between the wars:" saw.
I have begun cleaning it up. No etch to be preserved, alas.
Bob Summerfield posted a while back about using Easy Off oven cleaner to break down the old finish on saw handles. this is how it came out after the Easy Off treatment and some light sanding.
26 inch 8 PPI. the saw plate cleaned up nicely, just no etch. Too much rust and time. I will post more when it is done.
