The RC-456 is and assumed correct. The changer is just like in William's post, except this one it's not in a console. It is missing both idler and changer wheels, stepped shaft and its AC switch. But the Shure mono cartridge is OK and from above, it looks complete but totally different from any other Collaro I have seen.
Enter another Collaro, a "Magnavox- custom", about 3 years newer(?) super dirty and missing its cartridge. This changer was included with an AMP-175 and 55-series AM-FM tuner to be restored for a two cabinet 1960 Magnavox console. I started cleaning in earnest and just as I was finishing up, noticed the motor was 230 volts 50 hz

. In a panic, I began looking for an identical motor, hoping not to match with two players on my shelf that belong to other consoles. I also need a 3-pin female phono power plug with flat pins, not the "molex" using round pins thru the 60s.
Unlike later Magnavox changers, this motor DOES NOT use isolation grommets, mounting directly to the pan. The good news here is the entire casting and motor matches the RC-456, which I will further cannibalize. Fortunately, the motor is 120 volts 60 hz

, so I can restore the "correct" changer for this two-cabinet model.
