I think this saw is pretty old. My best guess would be '50's or '60's.
These were key years for home craftsmen and do it yourselfers. Power tools were hot!
We really weren't importing a lot of stationary tools in those years, but there were a lot of private label saws made for the chain retailers. Some of those retailers are now long gone or at least no longer selling woodworking machines.
Examples like Montgomery Wards, Western Auto and of course Sears.
Some of these old machines were well made heavy machines but their resell value is low these days.
When you have a chance to inspect the TS, there should be a name on it somewhere. The name will give you a clue to the original seller but maybe not the original Mfg. Some of the original Mfg have long been out of business.
Color means nothing on these old machines because some have been painted many times over the years.
Buy cheap if you can. Gather all the accessories and any extra blades you can.
If you don't have time to do it right the first time, when will you have time to do it over?
