Hey optical fans, trying to figure out the optical type of the Mamiya 80mm TLR lens. Looks kinda like a modified Tessar to me, but not quite. It goes (] [))( [)() single element, cemented pair, stop, cemented pair. The rear pair looks very much like the rear pair on a Tessar, but the cemented pair and then the single element doesn't fall into a Tessar, in fact I can find no other similar lens. Any help/discussion would be appreciated.
