Never seen a SS PB but the vertical hinged chassis dated back well into the tube era...I own this PB Roundy with the upright chassis.

I also once has a PB Teledyne hybrid that was a rebadged GE C2 table set.
PB was mostly a west coast brand, but did have a dealer in Wi...if there wasn't a dealer near you and your not In the west it will be highly unlikely for you to find one local or even in reasonable driving distance.
