I think it’s based on the Tessar, but is something different from what’s in the Hasselblad manual.  The cross-section is definitely different.  There are apparently at least two Tele-Tessar designs, with different numbers of elements.

I’ve not been able to justify the cost of a Planar Rolleiflex, though I’d really love one with a nice f/2.8 Planar lens.  Both of mine have the 75mm f/3.5 Tessar.  The older of my two is from 1936, the newer from about 1958.  For me the Rollei is more of a small lightweight travel camera, or shooting for fun, than a serious camera.  Sort of a “getting back to my roots” sort of thing, as I started with a Yashica 44LM TLR.

What I really need to do is spend the money and get my Hasselblad’s 80mm f/2.8 Planar C CLA’d, as the shutter on it isn’t accurate (or fast) at any speed. :-(  It’s my "serious work" Medium Format camera.
