Wells Gardner did build a lot of contract sets for general merchandisers such as Montgomery Ward, Gambles, Firestone, Western Auto...etc. In this area we had large Montgomery Ward store for many years until Mobil Oil bought them out and closed many of the stores and ran the rest into the ground. I run across a lot of Airlines and Coronados in this area as we also had a Gambles store and a Western Auto so we also see quite a bit of Truetone.
Montgomery Ward sold some really innovative or gimmicky sets depending on your point of view and example is the movie dial sets. Many Airlines came with chrome chassis, there is one set that has 2 chassis and 2 speakers and rivals the best of Zenith, Philco and others, I believe it was built by Wells Gardner.
Point of interest Wells Gardner is still in business, still an American company and traded on the American Stock Exchange
