HISTORY:
This machine was offered for free on the OWWM.org/BOYD, in 2008, by fellow OWWMer Kyle Mason (Medford NJ).
I luckily spoke up first. The saw included a 1950s Craftsman 16x30 steel frame tool stand, repainted black and orange.
Andy Houriet (Chalfont PA) kindly Ruckered the saw+stand to his place and Pottered it for awhile.
Rich O'Conner was nice enough to Rucker it to me at ArnFest08.
No further details are available at this time.

MACHINE:
Sprunger Brothers 20" belt driven jig/scroll saw, model JS20.
Serial number 74281, dates this machine to 1972, built in the Ligonier Indiana factory.
The rotary crank drive mechanism runs in an oil bath. The assembly is enclosed in its own housing and located inside the base casting.
The 2" drive pulley bore is parallel to the base and arm.
Recommended motor is 1/4 or 1/3 hp, 1725 rpm, with a 2½" pulley.
The body is a one piece iron casting. The table is also machined cast iron.
The machined steel chuck jaws have an index pin in the back of the slot. This pin aligns the back of the blade during installation (nice feature).
Only missing the air tube from arm head to roller back-up holder.

I no longer own this machine. It was given to a fellow OWWMer.
