Try one of the arbor sights. Lot of guys collect those old saws. The B was a big improvement over the A. 1950s era saw. Both bow and bar types though the few i have seen were bow type. Had a gear reduction drive on it. The REA had some of them in both types when I was a boy. Lots of noise, lots of smoke, lots of work is what comes to my momory. A steady cloud of blue came out from the area they were being worked in.
