These things were all over the place in the 50's. Skimpy little sheet metal or aluminum tables. They were a compromise at best.
An old carpenter friend of mine told me that when the first circular saws came out they were often fitted under a wooden table table and used as cut-off saws. They used a foot pedal to lift the saw.
He offered me his original saw from the 30's (iirc) sucker must have weighed 20 lbs !! Kinda wish I'd taken it, but you have to draw the line somewhere.
All the best,
