While glancing at my '40 Triumph today, InstructionsI happened to notice the Special section of the instructions and realized that a free game could be won if hitting the post number highlighted in the diamonds of the backglass.Backglass diamonds 6-10 I have noticed before, even though the backglass is screened to display numbers 1-5 in the diamonds on it's left side, there are no bulbs behind those numbers and it certainly looks as if no bulb sockets were ever installed. Missing sockets for 1-5The two backbox photos on IPDB confirm my suspicion. Oddly, the harness has 10 wires but only the 6-10 numbers have been soldered on the jones plug Jones plug6-10 sockets and only 6-10 are soldered on the step-up wiper.6-10 on Wiper You can see the other 5 wires taped in a bundle.
I'm still struggling to figure out why 3 of the 15 numbers won't light up on the playfield but the hit registers. Those same 3 numbers won't light on the backglass either. I also see that i am the only one registering this game on Pinside and only one other owner lists the game at the Pinball Owners site.
Surprisingly, the game is noted in McKeown's Pinball Portfolio(1976). McKeowns Triump[h photo
I just keep chipping away...
