All kinds of them out there . They are still common over here. They are on ebay weekly for instance. You may get the ebay buyers to ship to Germany. Forum members may not want to go through the time and trouble that international shipping sometimes imply. That is probably the main reason that the multiple people on this forum who have them myself included don't respond. Only posted because by your post it reads like you don't understand why people don't respond to your request. Best of luck on your search.
It is that easy to put the parts (if not too big) in a "standard" USPS box format and to ship them. Thats about it. I really do not understand why people always think they would have trouble. Freight cost can be calculated via USPS calculator or asked in the store. Thats may be the only thing which creates some extra work.
I got several parts in the time being from people living in the States with no issue at all. Tax and fees have to be paid anyways by me (when parts arrive in customs), as well as the part price of course and shipping cost. And you recently sent horns to GER. Believe it was not difficult, because you did it. But thanks for your wishes.
Ebay parts I saw so far, are rubbish more or less.
May be someone has some better to sell.
Thx
