Joe, many thanks for your answer! The Problem is: I only have the Numers on the Blade, except the 120, this is a SP3-0. I bought this knife and didn't get a certificate. The seller means, Buck didn't give out one for this knife. Can that be true? Furthermore I dont have any numbers. Here's the knife list with the translated date code:
102 made 1992
103 made 1995
105 made 2005
118 made 1996
119 made 1993
120 made 2005 (on Box 10-02-06)
Joe, I would be very pleased if you help me
Best regards,
Herbert
