I clipped that information straight off the Schneider site, but it tallies
with my Compur Repair manual:
Compounds were made in sizes III, IV and V (or 3, 4, and 5) but with several
variations of each with different threads, cell spacing, and whatnot. To all
practical purposes the shutter of my 300mm Xenar is a size 5. Only nerds like
me and experts like the late Steve Grimes "need" to know the difference.
Two of my other lenses are in Compound #3 shutters. A 360mm/f:5.5 Tele-Xenar
in a III 7+3, and a 210mm/f:4.5 Xenar in a "normal" #3. I have no idea what
the specific denomination of this one is, but I will probably find out in a
few days - now that I've become aware of the question...
