Very nice Andrew, have you made the bellows removable so you can change front ends ?
I've just restored an Agfa Ansco, well more just the woodwork & brass and it only has front shift, I'm going to make a lens board with built in tilt, I'd drawn some plans up a couple of years ago but noticed recently that Richard Ritter makes them the same way. You might look at that idea, someone posted some images of their 10x8 withone of Richards tilting lens board on the Large Format forum a few weeks ago, in Sept or October. Not difficult to make.
