[Leica] Opinions on a lens?

[photo.forrest at earthlink.net (Philip Forrest)]

I've recently acquired an old Adox Adrette II with a Schneider Xenon 50mm 
f/2 
lens in Deckel shutter.  I got the camera for just a few dollars in 
non-working condition for the sake of getting a hold of the lens and film 
transport to use on one of my many "Frankenstein's monster" camera projects.

Does anyone shoot with the 50 Xenon and what is your opinion of the lens?  
If 
it's a good performer, I have a few options:
        *Repair the camera to fully working spec (I'll have to find another 
parts                       
        body    for this)
        *Graft a LTM- M adapter onto the back of the Xenon lens barrel 
helical and 
        shim it to the proper registration distance for use on my M4
        *Set the lens elements in a user 50mm helical and use it with RF 
coupling       
        (I'm thinking of using one of several Russian lens barrels for the 
donor)

I'm looking forward to shooting with old uncoated "superspeed" optic from 
just 
after WWII and any advice you have to offer would be very appreciated.
