"Aristostigmat" ???

unfortunately, "Ektar" was simply a trade name designating the better
quality Kodak lenses, rather than a description of the lens
formula/design ;-( Richard Knoppow's comment of 27 Mar 2002 cited on that
page makes this observation too.

So while all Tessars should be 4 elements, all Ektars are not tessars, and
so some could be triplets as Feininger states (the cited source for the
listing). For example, the 105mm f/3.7 Ektar is a three element Heliar
(again, from mf/ektar.html pages), the famous kodak medalist ektar has 5
elements for 6x9cm RF, the 45mm f/2 ektar on the kodak bantam special
(28x40mm) had 6 elements, and so on.

But I will add a note with your comments to the page on the next update
cycle, highlighting this point some more ;-)
