Yep. Your Kirby definitely has been to the spa. The belt lifter is a replacement from the late 60s/early 70s. The bag is an aftermarket replacement. The cord is from a Kirby Classic and the handle grip cover is completely missing! LOL! The Builder's Plate on the fan case should tell you the model. But looking at the foot switch, it's going to be from a 505 (1945) to a 512 (1952).
