Not much more progress made...
Pop bumpers are partly back together...Ordered new lamp sockets & bumper caps...Not sure if I can find the decals which go on top of the bumpers, but will have to google. Also beacon lights back on and cleaned. The centre piece was painted an flat grey (almost undercoat colour). I sanded this and painted it silver. Just a pressure pack job. Came out OK. I'm also trying to find the "Police Force" decals which go on them. I may have to try a sticker place, but I'm not sure if they have the chrome colour which I believe they came in?
I will have to sort out the wiring again for the lamps in pop bumpers, then playfield is done....I've decided not to remove the mylar on lower pf. There are a few bubbles but I don't want to wreck a very good playfield just for that..If someone has done the 'injecting clear into bubble' method I would be interested?!
