We got an early 500 series Kirby.
The nozzle is specifically a 508 - 512 nozzle. I can tell by the lines on the front. As well as the rug plate.
The emtor is a 3C - 505 emtor.
3C - early 513 handle grip.
514 & 515 handle fork.
Aftermarket belt lifter.
All replacement red trim, bag, cord, etc.
That could be a 505, or it could be something newer with an older emtor on it. Not sure exactly.
