45 dates would be the only ones for meMy guess is because the serial number is in the second (alpha letter suffix) series, that was the incentive. Yes... collector grade anything has always been both more difficult and expensive to come by. Sometimes one has to settle for a item in less than desired condition if it is particularly scarce or hard to acquire, with the hopes of upgrading in the future. I personally would not consider buying any S84/98 T3 with such a blade unless it was a very rare variant and priced way below market.
Problem is that by some sources are bym Ferlach declared as super rare, so maybe this caused the price range, even the piece is here damaged by sharpening.
