I have a Ledsome 1000 with the manual foot pedal. There's an outlet on the side that's labelled "Compressor", so I assume there was a pneumatic option for this saw, but I can't find it on their website. Did that exist? If someone has one, would they be willing to take me a few pictures of the internals (specifically location and spec info of the pistons)? I would like to look into modifying mine.
