First and foremost Thank You all for your generous comments and encouragements, they are very much appreciated.
For those expressing reservations about the challenge of rigging this beast don't worry, be happy! My attempts to inject a little self directed humour into some of my comments often gives the impression of things being much worse then they really are....... I'm enjoying this challenge and it is quite "doable", however slow and easy is definitely required in the approach.

Prez, I agree with your comments; the cross braces on the front cabanes are on some diagrams, not on others, and the rears are a bit of a mystery as well. I concluded, after going through every photo I could find, that some aircraft definitely had them both, some none, some only front and some only back! I elected to install them all. As for the lines from the upper wing to the horizontal stab junctions I'm not there yet but I did note exactly what you described on the Instruction Guide Rigging Diagram. (One line or two each??); also that their attachment location specifics are very vague. I must look carefully at the other references.........
GCN, I agree that the tutorial on Bob's site is the best single reference however the diagrams are very vague concerning the termination points of some of the wires and a photo search is required to verify them.
Patrick, the method of mounting the upper wing on the cabanes first is the one I find easiest. If a "two bay" design such as this or the Brisfit I've found it more or less necessary to have the inner bay main struts installed as well, then the outers can be carefully "popped' in. I also find it easier to adjust the alignment of the upper wing laterally with the lower when working with fewer glued struts.
I have roughly 2/3 of the wing rigging now completed, hope to finish up today. I'll get a few photos posted once that's done before I start on the "Gitter Rumph".
Cheers,
Lance
