I am the proud owner of this fine specimen of a GSF400 GK75A.

I want to import it to Slovenia, but silly new law limitation require it to be an Old-timer.
The Hungarian Reg state it to be YoP 31.12.1994 for a vin number GK75A124149, which according to other exampkes i know makes no sense,,
1. Can anybody be so kind as to check the actual manufacturing date?
2. Is there a possibility to produce an official document that state the date to prove that?
Many many thanks in advance, guys!
Best wishes and fun motoring.
Cheers.
