Mike,
are you sure the liner was made from 'catskins'?
even (or perhaps especially) in Germany that would have caused an uproar! hehe
I do remember the type of coat you are referring to - green Loden - the lining (removable with buttons) is usually made from hamster skins (Maihamster), sometimes rabbit, and is beautifully warm & pleasing to the touch!
Unfortunately I gave one away in the early seventies when I moved to a hot clime (Kenya) & thought I would never need it again.
Very expensive item though!
Best regards from England
