If people are interested, I received via Facebook this very promising reply yesterday from Andy Bud ;
"Hello. I now live in Hungary. I still make the odd loom, and I have all of my resources here. They’re not too difficult to put together, but I only have templates for earlier vans (I haven’t done a later dashboard). But I doubt much of it is different. They’re a simple design. I guess it depends how desperate you are for one. In the past I have also usually fitted them, but that wouldn’t be so easy now. I also upwire them by us8ng modern wire in traditional colours and also relays for lighting and a decent amount of fuses."
I'm following up on this, plus he's already had two other people expressing interest. If folks on here are interested but not on Facebook, if you message me your van and year plus contact info, I'm happy to FB message that to Andy. I will also see about getting his direct non-FB info so others can contact direct.
