FSU original Barnack copy in comparing to newer FSU M39 cameras with removable backs

I use Summar all the time - I am starting to like it more than my summicron. It is a great lens. But curiosity draws me to FED f2 lens, and from time to time I see it relatively cheap (in Poland, and here as well). I can test it, play it a little and sell it without any loss.

Well, go for it!
The FED ƒ2 lens is a bit more compact when collapsed, since its essentially Double-Gauss in Elmar body, thou it sticks out longish than Summar when in use.
Here's a shot of the iridescent natural coating on the FED ƒ2.
