I haven't been this excited about something since I learned how to ride a two-wheeled bike.
After reading the comments about the possibility of the saw being cut down I went back to the basement and looked carefully at the ends of the blade.
The tooth pattern is the Perforated Lance Tooth style, and using my digital calipers I confirmed the blade is Crescent Taper ground.
The blade is 77 1/2 inches long and 2 1/2 inches wide at the ends.
I haven't found any photographs or descriptions for this type of handle hardware.
There are 18 raker teeth on the blade and a total of 86 cutting teeth. After cleaning the rust off the hardware and getting the castings down to bare metal, I noticed a couple of spots on the casting that had been painted at one time.
I have a question about dating Disston saws by their medallions.
From what I have read here and elsewhere, it seems that a Disston saw could be dated fairly well by its Medallion, as shown on the Disstonian Institute web site.
I have no idea what someone would charge to sharpen a two man crosscut saw blade, but I did manage to find an older guy my age that's willing to do it for /foot, which really sounds good considering the time it will take and the fact that everything is done by hand (I think.) I found one guy in Montana that would do it for /foot, but he's too far away.
Bill The last picture of the handle looks like a Disston 114.
There were no manufacturer marks or etching on the blade, and no manufacture marks on the cast handle hardware.
