Yeah I like that one too, I believe I shot that at 1/60 at either f11 or f16. I pretty much just guessed the distance and crossed my fingers, it didn't help that the wind was blowing. Then when I saw the final product I was like WOW... thats pretty good for a 65 year old single coated lens. My original plans were to seek out a Super Ikonta with the 3.5 Tessar, but I've decided I'm plenty happy with the 4.5 Novar. I'm still waiting to see how the uncoated Rodenstock Trinar on my Franka Solida does.
Edit: Just saw that Certo6 has another 521/2 listed for about the same price, with a 3.5 Novar.
