Looks lovely Martin.
I notice that the switch and wiring is exactly the same as mine was, before rewiring to 50's specs and switchcraft hardware and cts pots.
I removed the clear plastic from behind the pots.
Also there are no identification marks inside the pup cavity like yours.
I downloaded an image of a protractor and printed it out, and cut it to do my measurement as shown above
One question.
Is the TRC like mine in that it is not beveled but "stepped" in three laminates?
I can guarantee that this TRC has been in place since at least 1990 when I bought the guitar.
The issue is if it is original or not to the guitar's manufacture date of 1985, as this year seems to be throwing up some confusion due to inconsistencies, which have been partially confirmed by the last few posts..
