Promised update -- I finished the applique armour around the driver's visor, and while it's not as exact as I would have liked, we're only talking a1mm error in most aspects, and this is as fiddly as I can manage -- it might not look like it but there are 32 pieces of plastic making up this subassembly!
Here are the inner and outer armour layers plus their spacer bar:
The bolt heads don't show up here, they're burned out in the white of the plastic. Now the finished assembly on the model:
The bolts on the outer layer show up, the nine around the edges of the inner layer are fairly invisible here. Oddly enough, fitting the bolt heads turned out to be the easy part of the operation!
The only major detail remaining to build is the jerry can rack, which is a Verlinden etched set, and I'll make a start on that tomorrow. I'm hoping that she'll be ready for paint when my airbrush is returned, and I'll be able to run directly through to the finish more or less without interruption.
Cheers, Mike
