a Heliar formula calculated by Fred Altman and was essentially the same
lens used by the Kodak Medalist offered originally in 1941. The free-standing
lens was originally inner coated with calcium fluroide and in the mid-1940s
was coated on all surfaces with magnesium fluoride. The 105mm version
was available in Supermatic shutters initially and about 1947 moved
to the synchronized equivalent, the Flash Supermatic.
