Painting my 1/72 tiger today, anyone have any 1/72 scale tank pics? Or 1/76 scale for that matter..

Well, I have my 1/72 revell tiger 1 completed. I painted the tracks a flat black as well as the machine gun up top.

I now wish to make the tracks, (at the contact points of track to ground) apear to be bare metal. Is there an easy way to do this? I guess as far as weathering goes, I just need some pics. I know how to do it, but I need some general hints at the location of wear points etc. If it isnt too much trouble, please post some pictures of any 1/72 scale tank model. I'd like to see them all!

Regards,
Marc
