Skilsaw 857

[RetiredandBusy]

I have a Skil saw model 857 that I inherited. I've already used it fairly extensively, but I'm interested in knowing how to use the additional items in the photo. It has a second sled and edge guide and apparently a tool to use with the edge guide, but it's not entirely clear how to use them. Any assistance is appreciated.

From the lumberjocks sure (bilyo): It looks like an extra bottom plate. The only difference appears to be a couple of additional holes for something and the outter part to the right of the blade. This would allow cutting closer to an obstacle on the right of the saw. The chrome plated bent plate is an edge guide. It requires a beam or rod which fits into the saw; usually fits onto the base near the front with the ability to adjust the distance from the blade. I might have thought that the other long narrow piece was it, but the pointed thumb screw is out of place. I can't think of any purpose for that on a circular saw. They don't cut circles.
The pointed thumb screw is used with a Craftsman jigsaw. I haven't found the rod that fits in the saw.
