Good, some local help will be much appreciated. Here's a few facts on the case.
The address to which I sent my cheque, payable to Bernd Binder, is the same address he had in 2001, when he sent a sales brochure to Lemmink. At that time, he used the ID 'Kralle'. The phone number on the letterhead is not recognised today. That could have changed, I guess.
In 2001 his email was 'kralle2@gmx.de' which I posted to, but is no longer recognised.
His current Ebay ID appears to be 'Kralle900' which someone here determined via a Google or something (?). This ID appears convincing 'cos 'Kralle900' is auctioning lots of stuff right now, including Amiga kit and he's located in Albstsdt. That's the place I sent my check, as did most others here I believe.
I have repeatedly sent messages to 'Kralle900' via the Ebay members' messager system, but had no reply. That in itself is suspicious 'cos 'Kralle900' is sending and receiving Ebay feedback right now. I asked him to post something on AmiBench or Amiga.org to show us he isn't a fraud.
There was a 'Kralle1' or 'Kralle2' on Ebay a while back and that had only negative feedback, but there were only one or two auctions under that ID.
Maybe someone would be prepared to bid/win something trivial on a 'Kralle900' auction and use it to make contact? A lot of his stuff goes for a couple of Euros.
I have been unable to find a Bernd Binder at the Albstadt address I sent my check to. I have spoken with the only two Albstsdt/Bernd Binders in the German phone book. Neither is our man. Maybe he is now ex-directory?
I made contact with the only Amiga Computer Club I can find in Albstadt and they haven't heard of Bernd Binder.
There isn't a Roland Geiger in the Albstadt phone book, though there is one 'R. Geiger'. I don't think I will call that number 'cos the connection's too weak. Maybe someone in Germany would call it? ...eh?...Pretty Please!
I will be seeing my Bank Manager next week and I will try to get him to contact Binder's bank. We have his account number. In fact this makes the whole scam idea seem unlikely. Who would give away his account details if he were obtaining money by fraud?
It's all very queer ain't it?
