Hi Christian,
I don't know of a source for Fine Molds in Germany but I think Smartmodelling in the UK carries this line. Sorry I don't have a contact but you should look in the vendors group on ML for his postings.
For captured T34/85s, the Military Machine magazine had an article with some interesting beute-T34s, including a /76 with schurzen fitted to the turret. As I recall there is one /85.
You have a great website, I liked the StuPa pictures especially, thanks
regards
Don
