1957 "Turnabout" Swivel Desk Clock w/Alarm

1957 "Turnabout" Swivel Desk Clock w/Alarm
Orbros Model J-150
7 3/4" X 5"
I picked this up at a local thrift shop for three bucks because it works and looks pretty cool.
I posted this for reference ..... you may come across one of these.
You can find these with all sorts of pricing and the word "vintage" attached.
A page out of a catalogue was the most help... I figure the manufacturer made a ton of these and are very common.

Thanks Much for Looking!
