1936-37 Rolleicord Triotar Coated!?

[macfred]

I had a ROLLEICORD II TLR Triotar 75mm f/3.5 a couple of years ago - lens was equal / comparable to my Zeiss Ikon Super Ikonta III 531/16 - Novar Anastigmat f/3.5 75mm.
It was quite nice at f/4, but only in the center of the frame. At f/8 and beyond, the results were quite presentable.
Unfortunately the R'cord had a few other problems - I gave it away.

I wonder how it holds up to other well known ≈ contemporary triplets, like Novar and Apotar?
And how is it wide open?

Rolleicord II from 1939, f:4, pretty much wide open:
