[W&B] landscape lens with what type adjustment screw ?

[Milan Zahorcak]

Hmmm . . . are there two you, Dan?  
 
Have you tried to push or pull it?  The lens . . .
 
No doubt, the cuts are to form a flap which can be pressed against the inner
barrel.

 maybe its not gear cut....just cut to make it a bit pliable to allow the
screw to press into the lens?

Dan,
 
Bob is probably correct; it's probably a locking screw for the slip-focus.
 
The lens is likely to be Darlot, so if you have a #2 Hemispherique Rapide
somewhere, try swapping the locking screw:

If it fits,then it's probably metric, but very close to a NSF 10-32 which
aren't all that easy to find either.

now that I have Milan's attention...
 
I bought this very nice Anthony (GOC?) Eureka 4x5.

It is quite nice and has some details that differ from Larry's Eureka here:

Like a nice beveled edge to the front face and only 5 joints compared to
Larry's 6...plus other details I will bore you with later....

But alas, when it arrived, the lens adjustment screw is missing.  I would
have expected some type of radial or tang drive - not one screw..... before
a take it apart more, what type of screw is missing and how did it work ?
some type of worm screw that would move the doublet ?  Detail shot

The next shot shows the front of the lens off with cap, push in stop
(inserted) and friction fit retaining ring.
