Well that's... peculiar. I was thinking I had my Cadillacs down to a tee. Old boy Clements had a LOT of different vac designs. I guess it kinda strikes me as odd, why this one has ball bearings (or so the bag claims) and it's much earlier than mine, which has plain bearings. And then later Caddy's went back to ball bearing. It's not the war... cuz mine is prewar. idk. Any chance I could get a closeup of the center cap/ belt cover thingy? I'm missing mine and I'm kinda trying to figure what it's supposed to look like.
