I may have one of these for sale. It's a 703 (I think!) with 2 keys, it has a seperate choke switch, and is in good condition, with the exception of the little plastic panel that pushes into the side of the throttle lever (and covers the PTT wires) which has gone missing.
How much is it worth? It's with my engine at the moment, so I don't know if it's a good plan to split them!
But, I've sold the rib seperate to the engine, so I could do things bit by bit...
