I don't know, but one thing is for sure MB is not any better than JM or The Shadow or Congo yet its worth 4 times as much. It's just a matter of status in a collector's mind that has driven certain pins to a ridiculous price and the dealers are more than happy to oblige. I know a lot of pinheads who own MM from back in the day and still own them but would never pay today's prices. The re makes are a different story, brand new tech and brand new parts 8000 to 9000 while high seems more fair. ZOD
