Would this be original? The collaro looks vintage to the unit,and I know you posted that magnavox did not use the collaro until '54. Someone over at magnavox friends said definitly not! I need your opinion. Are these good turntables, seems to play 33s good but needs general servicing. rjh0566
Collaro continued to make the 53 "Sentinel" series into the mid 1950s, as well as the new 54 "Continental" series. I have seen a 53 in a Magnavox. The 53 "Sentinal" series was discarded when Collaro changed to 4 speeds, to be replaced by the 350 "Conquest" series.
There were two different Collaro 53 "Sentinal" record changers:
- 3RC531 (later the 53-1) had a 3-position size switch next to the reject control.
- 3RC532 (later the 53-2) had a 12" record drop feeler and a 2-position size switch (7", and 10"-12"). It could take intermixed 10" and 12" records, or 7" records played separately.
Other Collaro series:
Continental - 3-size drop feeler.
Constellation - 3-size drop feeler with plug in head and 12" turntable.
Conquest - Polysize arm tip feeler.
Coronation - Polysize arm tip feeler with plug in head.
Studio - Polysize arm tip feeler with plug in head, same overarm as Magnavox 800.
Professional - 1975 series with 3-size arm tip feeler, cue control.
One thing we have to remember is that the time the company produces a changer ends earlier than the time that changer is used in products. Manufacturers usually buy up an inventory of a product to be used by production for some time.
I was wrong about Magnavox not using V-M until the mid 1970s. For a brief period, Magnavox used V-M changers in portables. There was a longshoreman's strike in the early 1960s that kept Collaro record changers from entering the US for a couple of months. Magnavox bought some V-M changers to keep from having to shut down production. They used the Collaro changers they had left in consoles.
