Wonder if he'll copy and sell those photos as a separate lot?
rab2591, that money may be better spent elsewhere: It's like owning an antique car, the original Hammond is all mechanical parts that need to be maintained regularly. The maintenance and repair hassles alone can make vintage Hammonds like this as much of a money investment after the sale as the cost itself.
Having said that, and having played a simply beautiful, well-maintained B3 mated with the Leslie 147 last year which eventually sold as a perfectly working pair for $3,300 US, there is simply NOTHING like the sound a feel of a real Hammond and Leslie. One of the best instruments ever made. But like a vintage car, you need to have some time, money, and mechanical skills in order to keep it that way, unless you have a repair person nearby. Or if it's being bought as simply a collector's piece and won't be played, none of that is an issue!
The Model A was the model that was Hammond's most famous tonewheel organ before the "3" series like the B3 and C3 which everyone loves. An older version, basically.
