I need help identifying an organ

[beaverteeth92]

Someone in my area is offering a free organ. It's listed as a Hammond, but doesn't look like any Hammond I've ever seen. Anyway, here's the photo:

If anything, it sort of looks like a mellotron. Anyway, what is this? Thanks so much for your help.

Hammond made a wide variety of console organs for churches and home use such as this one aside from their more famous models (A100, B/C3 etc). The console looks like one of their spinet organs, but the manuals are arranged like a console organ. The first line of controls above the manuals look like drawbars and chances are the coloured switches control other voices. I don't recognise the top controls - possibly a metronome or recording function?

I know these turn up fairly regularly on ebay for pittance, but I don't know of anyone who's every played one.
