Casters for a Seeburg STD2 Entertainer

Any rubber casters you've used that will work for this model that you'd recommend?

Doug,
You want "rubber castors"??? Seeburg never supplied them, and I don't know if they can be found ! The OEM supplier was Bassick Castor co--now owned by Sheppard--you might search for them, either at a castor supply house, or on the web ?? Ron Rich
