I have to admit, Bob, that the description "panel saw" probably fell out of favour by the 1970s with the widespread adoption of modern hardpoint tooth saws and that my last panel saw was a 1 tonne Altendorf F45.
I was the youngest in our shop by quite a margin and some of the older guys used to describe tools in very old ways or used tools no longer seen, e.g turnscrew (cabinet screwdriver), rampin, nail set (nail punch), pig sticker (heavy oval bolstered mortise chisel), dooking chisel (plugging chisel), egg beater (mechanical hand drill), bitdcage maker's awl, etc which have lived on in my own usages at times but are sometimes a mystery to my (younger) colleagues
