Quoted from Pinball-DOOD:I know the wooden legs aren't original but my machine has red markings where the old legs were! I believe Gottlieb (like every other company) put any legs that were available that day on the machine during its production. These were money making machines and not for home collector. Most of these older pins show differences in terms of characteristics including artwork differences, parts used... so who knows!
I doubt it. A company cannot be that inconsistent - they were consistent unless the machine was a sample or prototype which I have seen use "extra parts" that were laying around.
The culprit is likely the 50 something years the machine has been around. I get games with the wrong legs all the time.
