Looks like a great kit! I'm also building a newer Tamiya kit for this GB. Tamiya gets such good marks for their kits so I'm anxious to see what the fuss is all about!
Had a chance to get started this past weekend and as usual I began with the cockpit. Nothing like some photos to show where a few touchups are needed and these will be taken care of next time I return to the workbench which has now been moved out of the sunroom and back down to the basement. It is getting a tad chilly in these parts to be sitting in an unheated room and a decided lack of sunshine.
Nice start to the cockpit! Did you apply the seatbelts as a decal? I've read of people cutting them out and glueing them into place with the backing on.
