Was wondering this myself just the other day...

Sounds like you just got opinions for answers. What color were the tracks on the original tanks when delivered from the factory? I would venture to guess that they were the same color as the tank (OD or whatever was the tank's main color)--corrosion was to be avoided so I think they were painted regardless.

I've seen Olive Drab tracks on restored M5 Stuarts, for instance. Most restorers are very anal about authenticity.
Anyone know for certain?
