This is so very cool! See, that's JUST the thing about Retro Lux's - or even newer Lux's - is that they LOOK simplistic (sometimes even not), but they are VERY complexly designed to aid in superior performance of the machine. Very cool B)
Besides savvy regarding attachment design, the real marvel was the automatic shut off. It was an adjustable mechanical device composed of a diaphragm and tubing that reacted to the strength of airflow at the bag mouth. As air flow lessened there, suction via a tube attached to the diaphragm increased until it created enough of a vacuum behind the diaphragm to cause it to pull a lever that opened the cover latch after which a spring loaded mechanism turned of the power supply. (I think I got that right.)
I believe there was an electronic set-up to achieve the same later on. If it is still in play, I do not know. Venson

Venson The New guardian ultra, rennies, 8000's, 9000's and a few other oddball models use a control board with a built in pressure switch.The 6500,7000,legacy use the the mechanical set up, The tube running from the bag cage to the winder housing was eliminated when the diamond J came out, this was the first machine with thermal overload sensor along with the HI-TECH 2100.Plastic body automatics do not pop open like the metal body unit.And the controls were moved to the top trim. It was thought that the tube was to keep the cordwinder cool, MOLE
