Thanks so much Ben for the timeline information - it's a pleasure to have things explained so clearly.
Looks like I need to find another Kirby to fit the mark 2 and a mark 1 to fit my 512...lots to do.
Appreciate the help,
Jay
Hello,
I have a Kirby 512 that I enjoy. Recently I was thrilled to find a handi-butler mark 2 set that seems to never have been used. Couldn't wait to try it out only to find it doesn't fit/attach to my 512 - Rats! It never occurred to me that the different handi-butler models would only fit...
