Hi Leonard,

The thing with the shutter I was remembering was that Lyndon Fletcher
had corrected me on the action of the "Open" position of the Speed
Graphic shutter.  On the Speed, that position only works as a "T"
setting.  In a dark room I think I could probably still get a pretty
good exposure by manually opening the shutter, triggering the flash, and
closing the shutter, but I don't think that's what you're after.  I
would be curious if the RB is different and allowed the use of the
"open" slit at something other than Time.
