Dan,
Nice catch! These are relatively rare machines; where did you find yours? I just picked up an S50 a month or so back after looking for one for a few years. Fellow forum member Jeff Duncan also has had one for several years.
I started a thread about it when I acquired mine that’s in the General Woodworking sub forum with a bit of information. Data is hard to find online about them, but a fellow S50 owner on OWWM scanned his copy of the owner’s manual that is available for download on my thread about the machine on OWWM or I’d be happy to email you the scanned manual.
Congrats on the new soon to be new shop space. It’s a few years off for me at a minimum, but I dream of moving into a shop with plenty of space, natural light and tall ceilings. One of these years!
