Here's an update: I made a template of the pickguard and will be mailing it today to Injun Joe. I took the guard off of my Tele Deluxe Reissue to make the template and while she was off I placed it on this 'steampunk' body to see how she looks - better than I thought:
The pickup cut outs are for full range pups and will of course be standard humbucker size on the final guard.
