Thanks all!
The kit is Revell (of germany) Kit 03039, and I believe it is out of production? :(
The kit started ok, but then problems were overcome by sanding and dry fitting. I got one piece of the headlight so well that it was a bitch to get it back apart and then glue it and put it back again.
The tracks are semi-indy in that there are 2 pieces of short length already made and you link up the rest, not much of a help having only one piece done.
Today I am detailing the smaller items like the chains, locks and wheels. I hope to finish it soon in the "clean" stage, and then give it a mud bath to match the box photos :)
Thanks for the input, more pics sooooon! (maybe this evening)
