Here is my Wright GS-4520 Reciprocating blade saw. I believe also called a Super Reble. She's a runner but for now is missing the toothed blade. Original paint was a bronze color, similar to an olsmobile engine paint, the paint has faded a bit on this saw. Lewis Brander.
Edited: This Reciprocating saw was originally posted as a GS-2520, but it has been brought to my attention that it is a GS-4520, so correcting the post. Does anyone know the years of production of this saw? Lewis.
Here is a pic of a friends Wright model B-520, that shows some of the toothed blade.
