I've translated some words in English and added some extra information. I guess now I've got only two new locos left on my wishlist: P8 and T3, the KLVM isn't that interesting to me. Probably another new item could be a series of Langenschwalbacher coaches in Ep. I. Märklin already produces these coaches in Ep. III version to combine with the BR 89 (T3, Ep. III) They would match perfectly with the T3 and/or P8 (depending on whether these items will be K.W.ST.E or K.P.E.V.)
I'm waiting for pictures...
