If you can mount it, it should work. The 2x3 Speed or Crown has very little movement to start with, the lens will cover the minimum and I suspect a good deal more stopped down, even if it is a Tessar knockoff (which I suspect it is). I have mounted 105mm lens off a couple of different folders on graphics lens boards and they seem to work just fine.

Let us know how it works out.
