Geoff,
My comrades overseas will probably hook you up with these links:

I am getting a bit carried away. Excuse me. There are a few more in the Track-link gallery section. If you have a favorite search engine try typing SOMUA S-35 in it and let it go. I have Steve Zaloga's Blitzkrieg book and a magazine article he did in Military Modeling. I could make a copy of it and mail it to you if you would like. I would say do the search engine thing first or cut and paste the links above in your browzer or give me your snail mail address or email me your phone number or all of the above. I wish I lived 30 miles from Mecca or from you for that matter. I look forward to seeing your S-35 project. I love this GB stuff
