This radio is a prototype for the 1943 production year. This set never went beyond the development stage because Philco switched to war production in 1943. Because of this fact, it's assumed that this is the only 43-720T known to exist. I acquired it from an eBay auction in 2001.

When cabinet material or color differences are apparent or suspected in donated photos, I have included additional photos of certain model numbers. Due to time constraints, I must rely entirely on the accuracy of information supplied by contributors with their photographs. As such, no guarantee is made that the model numbers presented here are correct.
