The only thing I know about these early Hammond consoles is that they
have just a preamp. Should have the same 11-pin connector as later
models.

Nope. If it is an original Model D, it has a 6 pin connector. The 11 pin
came MUCH later. However, if it has speakers built into the cabinet, it is
probably a D100 series rather than a Model D (and does in fact have
built in amplifiers-3 of them-rather than just a preamp). Model D was
built from 1939 to 1942. D100 series was built from 1963 to 1969.
