It's looking the biz Dale. I wouldn't worry about the wheel covers. Although they were a standard fitting, and virtually every 56th FG 'razorback' had them, they were removable, held in place by three studs, so that they could be taken off for access to the wheel itself and removal of same. I've been trying to find a suitable subject without the covers for one of my builds, and have finally done so for a bubbletop, but not a razorback, although I have seen pics with the six spoke wheels, mainly in the PTO.
Thanks for info on the Tandy punch set Andy, I'll look out for one. I've found a similar set from Germany, in a nice wooden case, but only down to 5mm.
