Very Nice collection of vacuums you have there. Cadillac is still with us-they make blowers,External filter wet dry vacuums(uses their blower as the power source) and plastics sealing and joining equipment.I too like how you can configure the Kirby to do other jobs.In their sales trainin g manuals it can be configured to 10 different machines.-Upright vac,Canister vac,blower,sprayer,shampooer,carpet fluffer,floor buffer,Suction only upright(broom mode as Kirby calls it)carpet dryer,inflator,the list can go on-think I have more than 10-even a leaf blower!Love the pix of your machines.When I was little my folks bought a Kirby from a DTD salesman(he was doing the Kirby Van campaign-knocking doors)They bought a 501 I think it was.It lasted almost 25 years. It got lost in a flood-if it didn't would probably still be running!Loved using it.My mom tells me of my dad using its sprayer attachment to varnish basement wall paneling-and made a mess of the machine.she mentioned he took it right to the Kirby factory(they lived in Ohio at the time and the factory was close to them) and they completely rebuilt it and polished it to be like new.I have been looking for one of that type for a long time!have the Kirby dealers here and others helping!Would also like to have a Kirby 1CB1-the early ancestor of the 500 series.Truely a cool machine.
