Looks nice.  I think that Hammond I found at the thrift store is a 70s 
model.  Anyhow, I found a pair of keyboards off ebay just yesterday from a 
1971 T-series Hammond.  Now I won't have to dispose of an entire organ 
just to get the keyboards.  Although, having an octave of pedalboard 
would make for another fun project.  One thing at a time!  I'm not sure 
how good I'd be at rewiring the busses, so I'm thinking about an optical 
or magnetic solution.
