Found a vintage car wash and the vacuums are D&S with the same pattern as this. Any clue?

I’d say it’s a Blaster. Just kidding . I don’t know. Our industry has had and may still have some homemade/backyard manufacturers that find their way into a few installations here and there.

Update: With the other location owned by the same person having a Southern Pride Turbo, and the SS equipment here being Southern Pride, I have discovered from an old advertisement that this is a Southern Pride Fast Tracker Adjustable Wash.
