Yes, I wouldn't mind if I had that Jupiter lens still. That one - as well as
the Russar 5.6/20 lens  that I have got - has got a tail-end that doesn't
allow to use them with CL, and maybe M5 because of the moving metering cells
in these cameras.

MArtin, et al-
Well, I got a nice Jupiter-12, a '78 model, and I was impressed with the
performance, it seemed on a par with my Summaron which I like a lot, but it
is not a retro focus design, so with the large 'tail-end' you have to be
careful mounting or dismounting so as not to mar the black anti reflection
coating on the edge of the element that stick out the back!! I think that
messing that up could lead to some serious flare or loss of contrast. The
upside is that for about $100 I got a nice 35mm lens, AND an auxillary
viewfinder!!
