Loch,
The standard body wood on Elan basses was maple.
I think Danno's Elan above has the standard Elan controls (vol, pan, filter + Q) and the one at Willies has what is called Elan Plus electronics (essentially what you get with a standard Europa/Rogue these days).
I have no idea about the string spacing and beware because as you know, string spacing varies widely on Alembics (based on the request of the original owner).
