This one has two hand-wheels below the baseboard. One raises and lowers
the 
head assembly using two chains that run up and down the inside of the main

column, and the other wheel  moves the bellows (focus). It has another
pair 
of smaller hand-wheels on the horizontal sup****ts (of the triangulated
head 
sup****t) to move the head to and fro. Today I am measuring those parts to 
see if I can add a belt or lightweight chain drive from one of the smaller

wheels to drive the other: this would allow the operator to move to-fro 
using one wheel and obviate having the enlarger sit 30 inches from the
wall. 
(Or a person could just disengage the worm-screw and push/pull by hand.)

I would very much like to work out a remove F-stop control. Will think
about 
it.

There are mounts for other things such as the red filter rod which are
empty 
right now. And an odd part that I cannot figure out. If I can get a
digital 
snapshooter I will make some pictures and post the address.
