Hmmm, interesting. You probably know that there are many ways of supporting vines, and in fact many ways of growing them too.
I'm going to opt for a more modern way with concrete posts made from cook's matches and fine nickel plated wire. The vines will also be grown in the modern way as a sort of upside down L where the shoots grow up from the horizontal bit. Yours will need to be the five branch type I guess. Vertical trunk with two branches off either side, then another two further up and finally one vertical at the top.
Classic cars deserve classic wine!
The vineyards around me have both sorts of support and both types of vine style.
I'm watching with great interest.
