The filter rod was also used to hold the shutter. The
original was a two blade arrangement similar to a Packard
shutter worked by a foot pedal. Not all had the iris control
and I don't know the details of how it was coupled.
One option was a condenser lamphouse with about 14"
condensers and a mirror arrangment for the lamp. These had a
focusing control for the lamp on the housing and its
possible some had a remote handwheel for this also. I wish I
could find my catalogue but it got boxed up. Time for some
garage cleaning I'm afraid.
You probably need a five foot ladder to go along with
the enlarger.
Saltzman also made a very heavy, geared, tilting
baseboard for perspective correction. I've only seen
pictures of these.
