Hi Everyone,
I am back on the list after a trip to Liberia in November and for a
while too much to do to sign back in earlier.
Just purchased another nice Contessa folder (Synchro-Compur) and a
Practica FX with shutter problems, but a WL fiinder with unique slide-
in prism viewer and 2 lenses, a Schacht Ulm Travegon 3.5/35mm and a
Steinheil München Culminar 4.5/135mm. The Culminar is finished in
gorgeous matte chrome. Looks very much like a my Leitz Elmar 4/135mm
and, like that lens, it has a removable lens head, albeit with a
different thread then the Elmar/Hektor lens heads (Marc?). Both
lenses are in "M42" (Contax S, Practica, Asahi P. thread mount).
The Culminar's focussing helicoid is very stiff. Anyone know if
that's easy to fix? It would be a nice lens to use on an AP Spotmatic
etc.

The lubricant in the focusing helix has hardened up. I've found
that standard grease down't work well, the stuff used seems to have a
particular viscosity so that it has some drag. I don't know what the
right grease is. A similar grease is used on the focusing cams of the
Rolleiflex.
I would not try to get solvent into the helix to free it both
because it may make it_too_ free and because it may work its way into
the lens cells. I don't know who repairs these things.
