Rock-ola MO20 MH20 WI20 WR20 differences (1938)

[Marcel Bogert]

Anyone have any info on the Monarch and Windsor models Rock-Ola made in 1938.

I was always under the impression these were just 2 models, apparently there were 4 as far as i can figure out the difference is just the cabinet finish.
No data available to confirm.
Any technical differences i believe the MH en WR are somewhat 'cheaper' versions, no pop meter for example.
Again no data to confirm

What is the so called borealis light-up supposed to be is it a moving light or just some fixed diffuser setup.

Hi Marcel,
The only person I know that's still alive today who might be able to answer this would be Bill Butterfield-- he's listed as a parts supplier in our FAQ's section-- Ron Rich
