I could buy me a Liberty Belle https://www.ipdb.org/machine.cgi?id=1438 , a pin I played in my Youth. I can play the pin but it has some bugs. I do not remember the rules --- do You have a fully running pin and can explain me a feature ? The schematics is a bit strange ... Here https://www.ipdb.org/showpic.pl?id=1438&picno=9635 on top and on the bottom of the picture we see "5 points or 50 points" - in my pin this does alternate - sometimes, hmm. In the JPG I show (squezed a bit) the schematics - I see (my marked green) the wiring "alternates as the 0-9 Unit steps" - but "my marked orange wiring" - what is it for ? --- the "U", "V" Relays pull just a short time (for the Roto-Units to turn) - the "X" also pulls just for a short time.
Do You have a fully running Liberty Belle and can tell me about "JPG, my marked orange wiring" ? Greetings Rolf
