This is partly inspired by a comment elsewhere from W-J about using a
Russar on an old Leica body. FWIW I recently got a rather nice but used
Leica IIIC which I like very much. I didn't get it specifically for IR
photography, but since it was only UKP 195.00 its IR potential may be of
interest, if it has any IR potential other than EIR, that is! In
general, the great advantage of a rangefinder for b & w IR is being able
to use opaque filters easily. Not having ttl metering is no problem
since with darker or opaque filters it isn't used. A screw Leica is a
bit of a culture shock after an M6 though, particularly the film
loading, which may not endear it to those who need to do it in the dark.
I'll try this sometime, but it may be too much hassle when I could just
use the M6 instead, which can be loaded by a total idiot in the dark
after drinking too much and getting beaten up on the way home... Well
almost. 

Loading a IIIC or any early Leica for that matter involves cutting the
film leader to about half the full width for about three or four inches
(can't remember but I sort of do it by sight now) and pushing the tip
into a separate spool which is then put into the camera through the open
base at the same time as the film spool, with the narrowed leader
joining the two. The instructions do say that two sprocket holes should
