Montgomery Ward radios were made by other companies, labeled as "Airline" and sold at Montgomery Ward. I have several and all are of good quality, nice looking radios. When I need a schematic, I must search through a list of documents of radios made by various manufacturers to find a match. I identify the chassis by visual inspection, tube complement and layout.Generally, radios like these have more intrinsic value than extrinsic. You can often pick them up on eBay from $25 to $50. Some models, like (Zenith) TransOceanics go for a little more, maybe $100 to $200. There are some collectables, older models and some novelties, that sell for more. But generally, the dollar amount they'll bring isn't real high. I think these old tube radios are great collectables, but more for the nostalgia than the dollar value.
