I own a Centigrade 37. When buying it, I was surprised to discover that the serial number was 01003 S, which means that this machine was surely the third one to be built. The color of some details of the back-glass are different (pans of the blond girl is grey instead of red on the standard version). And the technical scheme is hand written and not typed. Does it means that this pinball has a higher value than a standard one? Thank you for your advices
