Steve Evans of Jacksonville Guitar Center in Jacksonville, Arkansas contributed these fantastic pictures of some really nice early era guitars and amplifiers. His pictures and descriptions of these amps helped to further shape the history of pre-1950s amps. Details about them are found at this history of 1937-1947 Dickerson Amps.
These are the nicest examples of the early Dickerson and Fators amps that I've seen.
