Yes, you might have seen something similar in front of your local 'five & dime' store w/a coin feed for a bumpy 2 min. ride complete w/'real jet sounds.'
Yes, a flathead 45 it looks to be, but not mine, I just found the pic on the web and thought some members would get a kick out of it. I always liked the dime store rides as a kid, something from the 1950's. Jean Shepherd probably wrote a short story about the rides, or mentioned them at some point (the author of 'A Christmas Story.') If you're ever in the need for a good time reading and laughing, get ahold of Jean Shepherd's books, either from an online source like Kindle, or the old-fashioned way, from your library. Playboy used to run his stories regularly, they're filled with all-sorts of memories if you grew up in the 1940's or '50's.
