I've seen many of those power nozzles in use. My family and friends had lots of Electroluxes. Electrolux was notorious for mixing and maxing components and for overlapping upgrades. Sometimes new machines were introduced with old power nozzles and sometimes new power nozzles were upgraded to old machines. Not to mention all the small changes like handles, wheels, styling, etc. etc. It's so hard to say which PN went with each machine. My aunt had a Hi Tech 2100 with a PN that looked like reply #9... My best friends mom had a Silverado with a PN that also looked like #9 with dark gray coloring. My sister's friend had an Epic 6500SR with a PN like reply #37. You can rest assured that Electrolux belts are famous for durability. They advertised them as being made with rubber mixed with crushed glass to make virtually ubreakable. It's very hard to destroy an Electrolux belt. Lux power nozzles combine numerous features into a very slim package that slips under most furniture. Amazing engineering, really.
