From what I remember a kid, my Mom had a 518 and the handle was filled with quarters, from what I remember her saying was that every time you vacuumed you were supposed to put a quarter in the handle and at the end of the month you put the accumulated money toward your monthly payment. As far as I remember all Kirby's had some sort of piggy bank on their vacuums with the exception of the Dual 80, that was the first Kirby to have the new Delta handle and it just had a specked decal back there. Ben from Oregon should have an answer on what was the first model to have the piggy bank on the handle.

The Dual 80 was the only Kirby to my knowledge NOT to have a bank in the handle. Ben in Oregon would know best on when the first bank model came out?? 

Sonny, your wrong, my mothers 518 form 1958 had a slot in the handle, she used to fill it with quarters. I don't know how far before that they started?

OMG Sonny, I have been a Kirby Area Distributor since 1977, I know Kirby's. Check the back of the handle on any of the tubular Kirby handles and there is a slot just below the vinyl handle grip where the coins go. Check it for yourself before you make claims that you know nothing about.

Thank you Dan !!!!!!!!
