Zenith experts....help ID a radio !

[anden]

Thought I'd try Audiokarma's radio forum to find info on a rather unusual Zenith wood tabletop from the mid 1950's. It's AM + 2 shortwave bands. Has 6 tubes with a 6K6GT output tube, is a transformer set, not AC/DC, 3 speakers, an 8 inch & two 3 inch drivers. Chassis is marked 6Y61B. Cabinet is the same as the model Y832 AM/FM of 1955.

On another radio forum - folks thought everything from it being an Export, to a domestic set that did not sell and was discontinued with few made, or a millitary sales unit.

I even wrote an article for ARC on this radio, but have never figured out exactly what market this Zenith was sold in. A company archive or internal documents must have details - Anyone have Zenith reference material from the mid 50s that lists this radio?
