Time for an update on this thing!
Since the last post I coated the countersunk neck screw holes with super glue, slightly expanded the trem top opening, fashioned a bracket for a recessed neck-on switch and added colour for the finish by airbrushing on gold, 'tan' and dark brown Angelus leather dyes. I'm happy with the appearance so far for a 1st effort.
Since it's just sprayed on dye and not rubbed in I'm hoping using Tru oil for the finish won't shift too much colour/grain filler around and I'll need to consider what's best to apply/rub it in with. Here's some progress pics. The camera flash probably makes it brighter than it really is - the real colour is about what I was aiming for though:
