Well....here's a pic of the setup I almost bought several year back. If you look close you will see the organ says "Hammond" above the center of the lower keyboard.
The seller was the second owner and had gotten it with somethig needing repair, etc. but said he got the entire rig, as pictured, from the original owner. I'd have to search my email archives...don't recall if he said who he got it from.
The picture that you posted is s little fuzzy. I'm sure that the amp head on the Leslie is a power amp, but can you tell what amp is on the organ? Is is a Sentura I or II?
