Comments:
This saw was handed down to me by an acquaintance who was no longer using it and wanted to reclaim his garage space. His father had owned and used it for as many years as he could remember. Although it is designated as a metal cutting saw, this saw did have a wood cutting blade on it when I received it (and accumulated sawdust in all the usual catch-spots).

Some things to note:
The table does not tilt, but is locked into position perpendicular to the blade. It attaches in the front to the cross bar that is in the place you would normally see the trunnions, and locks in place in the back via a pin.
The table is large for this size saw: approximately 20" x 22".
The small drive pulley is direct drive, which gives approximately a 2000 sfpm blade speed as setup when received. (The motor is 1725 rpm; the motor pulley is 2-1/4", and the drive pulley is 7".) When I received it, it was set up to drive this small pulley.
If a belt were run to the large (back) pulley instead, the blade speed would drop to approximately 200 sfpm. (1725 rpm motor. The 2-1/4" motor pulley pulls the 14" back pulley which direct drives a 2" sprocket that pulls the 10" drive sprocket.) I haven't run it, but it appears that the low speed sprocket setup slips when the high speed pulley is the one under power. I don't know if that is supposed to, or if there is a pin that is sheared, or ???.
The wheels have an interesting profile with a large lip on the inside face only. I don't know if they were designed to have tires, or to be run without so the blade rides directly on the rim and uses the lip to hold the blade in place.
What appears to be a solid panel behind the lower portion of the frame (you'll see it in the 3rd photo, below) is a heavy card stock. There was a similar panel attached to the upper area. These match the profile of the wheel cover.
