The only one I've ever seen, in many decades of yard sales flea markets, antique malls and shows.
Two turntables in one player, to play 45s with either a small or large hole.
Case is like new.
Turntables turn, but are sluggish, after setting on a shelf for years.
Tubes light up, no loud hum, but I could not get the radio to work, or the amp for the phono.
Probably something simple to repair, if you can do it yourself, or can find someone who can.
Has the famous "Cobra" tone arm, though rather miniature in size, compared to the changers that played all speeds.
I can meet a buyer at some convenient location in the Des Moines area, next time I'm up that way.
