OOooops is right Thanks for the correction WW2 and Carl for the reference. Here is one for the both of ya Sorry for the miss information. Just went through a stack of pics that I TOOK! and they all look like steel to me in my own photos. Went through a few books, has to be some rubber somewhere, and they also look as if they are steel Good thing I have only built 2 Sherman's so far. They were of a special variant.
So what I meant to say:
WW2 - Great progress on your Sherman so far and I especially like how you depicted the steel support rollers Have known individuals that have done those incorrect before, NICE JOB
