Mainly that it is not an air spaced triplet using FPL-51 as Thomas claimed but in the masters own words "It is an oil spaced lens using FPL53 center element" and I have kept the email to prove it should I ever need to . Just inspecting the objective lens with your own eyes it seems quite obvious too.
