Here's what he has to say about the 210L
"The L series was Fujis low cost, entry level line. The 300mm and 420mm L lenses were both in big, relatively expensive Copal #3 shutters. When the EBC multicoated 300mm and 450mm C series models came out in mid-1982, in smaller, cheaper Copal #1 shutters, there was little reason to continue offering the 300mm and 420mm single coated L models in spendy #3 shutters. So, I think it's fairly safe to assume neither of these models were ever offered with EBC multicoatings. With no alternative in the C line, the 210mm f5.6 was the lone member of the L series to survive past mid-1982. It is still listed in the D.O. Industries Price List dated March 2, 1988. I am currently lacking official Fujinon literature between 1983 and 1996, so I'm not sure exactly when the 210mm L was discontinued, or if it was ever manufactured with EBC multicoatings."
