I purchased this receiver in August 2005 from fellow collector Jay Volke while attending the ARCI's "Radiofest" in Bolingbrook, Illinois. This set is essentially a NOS piece since it had remained in its original packing box since 1941 and there is no evidence to indicate that it had ever been used.

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.
