Like this? From 1965 AR article.

There is also an entry in Crowell (1919) stating that 42,607 "Sights, optics for Telescopic. Rifle Model 1918" were ordered from Eastman Kodak however none were delivered as of Feb 20, 1919.
Eastman Kodak was to be the lens subcontractor for the 1918 Scope. The scope itself was based on a Winchester design.
There is no mention (in Crowell) of an order for the rest of scope. I suppose its possible a few hundred were put up for testing.
The very heavy brass adjustment knobs tended to break off after a few hundred rounds.
Except for the scope the rifle was way ahead of its time.
