H. Disston Sons No. 7 antique panel saw. It is the first original saw produced by Disston Sons between 1840-1928. In 1928 it was replaced by D-7. The medallion on this saw dates it to between 1896-1917. It is made with high carbon steel and sports a beech handle with 3 sawnuts. It is sturdy and with plenty of life left if you want to put it back to work. It is an estate find and in the same condition as found. Please refer to pictures for additional condition details.
