Bellows minimum 2 1/2 inch to maximum 13 inch!
Model C 4 inch square lens board
Limit lens rear element diameter maximum 3 1/4 inch = 8,26 cm .
1 7/16 inch = 3,6 cm forward from lens board to closed bed.
a)
remove the
camera back.
Set the curtain at “O” full open aperture and mark the position of the top
curtain strut on one site of the camera body.
b)
From the
curtain setting plate (upper plate), remove the 5 ( #1 x ¼ “) oval head
screws.
Note
any spacer washers that may be replaced at either end of the rollers.
c)
Check break
spring of the escapement ( in respect to its latch of the master gear stop pin).
Hold the shutter release lever back and rotate the winding key until the stop
pin snaps beneath the flat spring and against the escapement- it should not be
possible to reverse the winding key and force the stop pin back under the catch
end of the flat spring. This spring should latch about 1/64” below the top of
the pin. If it has been necessary to remove the escapement screws apply a touch
of Glyptol cement to the threads before assembly.
A=two escapement screws. If they have been removed, apply a touch of Glyptol before assembly.

d)
Lubricate the
master gear stop pins with wax base lubricant and lubricate hole when the top
gear stop pin is stopped against the escapement.
e)
Set the curtain
setting plate so the “O” appears squarely in the indicating window when the
top gear stop pin is stopped against the escapement.
f)
Wind the
curtain so that its top strut lines up with the index mark on the side of the
body. Hold the winding key against the stop and reposition the plate; check the
site play of the roller and if more than 1/64”use spacer washer 20600 at the
case bearing end of the shaft. Reassemble two screws, test run check the top
strut and index if satisfactory, wind the curtain and release- note the position
of each curtain strut in relation to the inside frame. If necessary adjust by
raising or lowering the pinion gear on tooth at a time.
