#50 VINTAGE, Fat-Boy Pull Chain / Paddle socket shells, made by “P&S”…. The shells are labeled ” 250 W 250 V P&S PATENTED “……. These shells have a solid ring at the end of the shell…… These shells are a heavier gauge brass than the “Uno Threaded Shells”….. All have a headless cap screw, all have been stripped of old paint and lacquer…….. Also, I gently brushed each shell by hand with a very soft brass brush to remove any cleaning reside…….. Ready use in your restoration or steampunk project….. Check out my other listings for more lamp parts…
