Joel sells Spicer mounts.  See his web site for the fantastic variety 
of sizes offered.  8-)  Also, Q-Vu sells the most common mount which
is suitable for paired TLRs or slide bar 6x6 pairs.

Could you sketch up something?  When I look in the back of my Sputnik,
I don't see much room for baffles.  I did notice a lot of low angle 
reflection off the shiny surfaces.  That got me to thinking maybe that's
the source of some of the softness of the images.  I could paint the
chambers flat black or install Edmund telescope flocking, I guess.  I'd
like to hear more about this before proceeding.

Thanks,
John B
