Yes, all Xenars for the Rollei TLR's were of the four element design. 3,5/75 (and a few 4,5/75 for the late Rolleicord II).

The 2,8/50 Retina-Xenar from the 50's has four elements.

Re: Can't afford a Rollei
I wouldn't generalize so much...

Of course none of them was ever fitted to a Rolleiflex, but i have read of other alternatives in this thread, so i guess that i'm not going totally off topic.
There are medium format folding or reflex cameras with very good triplets, like a Meyer Trioplan, and with some luck you could even find one with the best of the breed, a coated TTH Cooke lens.
A nice Rolleflex with Planar would come cheaper though, as i jave just seen a coated f/2.8 5" Cooke triplet being sold for about 1400 USD on Ebay!
The fact that some of those lenses are still used to shoot 35mm footage for big budget movies speaks volumes about their quality...
I love some triplets for their flexibility (optical "signature" wide open is different from when the lens is stopped down).
Whatever... optical quality has more to do with tight mechanical tolerances, the use of computers to optimize old projects, and the introduction of better coatings, than with the type of optical layout.

The Meyer Trioplan is awesome. I have two for LF. Very smooth and I don't care if it's not the sharpest lens ever as I only enlarge 2-4x on 4x5 film. It's just real nice and my first choice of lens for 210mm range. (Second is my fuji tessar) I've got a plasmat nikkor I should sell because it doesn't get used like the Trioplan and Tessar.
