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?

I too, was'nt aware there were any counterfeit Koetsu's. Do they exist and has anyone been unfortunate enough to buy one?
