Mint looking pin, hope you got some room to move around 
There are two more pins in the garage since you were here, Luke. Another one coming on Sunday
JM is an awesome game, in fact probably the fastest machine i have played, the orbit loops are insanely fast.
Do you reckon the white base is factory Nino? I've had 3 and none of them have been white - also with the extra supports in there (between the sides and the base, i wonder if someone has put a new base in? Or it may be an early or late production run...
Also, since you have the transformer removed, i would put a piece of rubber between the transformer and its mounting plate. This takes out the loud hum that comes from most of the late WPC models with the transformer mounted in the back
It is the first I've come across with a white base (that I've paid attention to). I'll keep a lookout with my next few games.
The loud hum is very annoying and it is because it is only an issue with the transformer jumpered for 240V 50Hz. Whisper quiet on 110V 60Hz. The first thing I did was place two rubber strips under the mounting brackets and it is a lot less audible. My CV is the same.
