What year was the Denon 103D discontinued?


One of my favorite cartridges is still the Denon 103D, although none of Denon's later models interest me. I know that it started being imported into the USA in 1977, but does anyone know what year production stopped?

Denon USA still had DL-103Ds , in stock, as late as 2002. I believe they STARTED making the 103D in 1977. I bought my first one in 1980, stateside. No data on when it was discontinued, but- IF you still have one; this may be of interest to you: (http://www.eugenehifi.com/VanDenHul/htm/van_den_Hul_Cartridge_Retip_Repair.htm)
