2003 first batch tiger 1 mid still fiddling with it
Hi Stewart
Dave offiler has a realy good blog on his build and in it he said
he scaned the detail from the war and peace book on the sdkfz 7
and fiddled with it in photo shop and printed the dials out.
This looks to be the way to go and its a realy good site and a realy good book.
his blog is http://www.offiler.demon.co.uk/sdkfz7/
I would say that all the info you need can be found here also on Paul Willis
web site.
