That's a very nice Pinbot to start with! I've never seen the stickers actually on the game, although I've seen them sold separately a few times.

I'm always impressed when someone can do their own artwork restorations, I lack skills in that area.

Don't forget to fuse the 2 bridges in the backbox, the last Pinbot to come through my shop didn't have the bridges fused, and I had to rewire from the transformer to the bridges because one of them shorted.

I'm hopeless as touch up work - but I might give this a try, as it does not look that difficult, and the sections are hidden from view. I will go through the process of checking boards etc and I will fuse the BRs - I always follow this step on all WMS machines.
