It’s definitely not a secret! I have projects backed up for months. Currently over 100 just waiting to be redone. I purchase in bulk whenever they come up. I get emails from folks all the time wanting stuff gone whether it be barns, I bought the ESSCO collection, other collectors, etc. Facebook is a wonderful market for vacuums as well. In the Midwest or East Coast people just have to be quick because I probably saw it
Wow, great job! I had one of those for a day several years ago, I won't bore ya with the details but the previous owner "rewired" it, did an amazingly horrid job, and it shot sparks. That one got returned real fast.
Believe 1930-1926 is the year range on the model.
I see you upgraded to the M18 impact and drill. That could be how you get them cleaner and faster with M18 over m12.
The very first model with trolley wheels and a lower attachment port, and the one with the solid wheels. Below are two pics of the very first model Apex, which had similar wheels.
Apex began in 1918 after Frantz Premier sold out to General Electric. Carl Frantz started Frantz Premier in 1910 to manufacture Jim Kirby's first production electric cleaner, which was the Frantz Premier. After he sold to GE (who was making the motor for him), he began Apex with that wonderful inclined and divided nozzle. I have tons of the advertisements at that time as well as I have Stan Kann's Apex A-3 which he gave me before he passed.
