Frenchy, Doh yeah just noticed when you pointed it out. Mabe thats why the tracks were so tight. I'll have to go over the destructions later and see where I buggered it up.
Gino, Unrealistically rusty? Usually I'd say yes but from photo evidence as supplied below by Dustin its accurate, though some of the rust should of been a darker. APU's built per Trumpeters instructions. TC's 50 mount? Pardon my ignorance on that one and thanks as always for the correction and information

Dustin, yes thats the one. Wiki has more pictures of it thier image section.
Richard, agreed.
All up I could of added some sand wash to the tracks and darker rust to both the tracks and the drive wheel but in natural lighting its not as light as it shows in the photos. I think I'd like to revisit the same subject with RFM's upcomming Abrams with interior to really do it justice.
