how to spot an early Koetsu


I just purchased an old turntable, on it is an old Koetsu rosewood cartridge.Now is it real or fake. If real how old can it be? Sound is great, all things point to a mark 1, the only thing that doesn't look right is the serial number. The number is etched on the top metal part of the cartridge where the screws go in,the number reads 911 75,thats it no japan either.So can anyone help me out here?

try getting in contact with Koetsu, or their U.S. importer or a authorized dealer. i just bought a used Lyra argo i and i called their U.S. importer gave them the serial # and they told me when and where it was bought new and sent me a stylus guard for free!
I too, was'nt aware there were any counterfeit Koetsu's. Do they exist and has anyone been unfortunate enough to buy one?
There was a similar serial number ( 92862 ) sold on ebay - item #5877293558 . It was said to date from 1991 . It seems to be quite a late serial number probably from a period just before koetsu ceased to operate as a commercial company for a while in the early 90's . Don't think it is a Sugano Senior serial number unfortunately . I have never seen an actual fake koetsu but there are some blacks painted to look like urushis out there . Ian.
