Chris,
I don't mean to be a buzzkill, but you should've asked before bidding. I do not believe that is a tonewheel Hammond but rather one of the later transistor models. To be curt, don't expect it to sound anything like a Hammond B3, if that's the sound you're going for.
The tonewheel organs to look for are the C2, C3, B2, B3, any of the A-100's (A101, A102, etc.), to a lesser extent the L-100 or H series, or even the M2 or M3 (although those lack decent bass, but they are good to get going on). Anything else is really not worth the investment. Anything with a "built-in" Leslie is not going to be a tonewheel organ.
Sorry.
