Back saw 10700-T1 bio
Cast steel, brass and wood, 15 3/4" long with 12" blade, signed "POOLe"? and "STAN FORTN & CO SHEFFIELD" and "Double
refined spring WARRANTED" with the brass signed "H. DISSTON & SONS PHILADA".
English-made spring steel has been processed by Henry Disston & Co. into a saw. The marks on this saw are a puzzle
because H. Disston & Sons is a later signature and by this time Disston was producing his own cast and spring steel.
