A couple years ago, a very generous participant
of the MF3D group sent me a section of ground
glass with which to adjust the focus of my
Sputnik. It has come in handy on so many
occasions.

I have since come into possession of about
a dozen sections of similar glass. If you
would like one of them, send me a note off-
list with your mailing address and I'll
send you one.
