At a glance and without looking up the drawing number the stampings describe use on a DeHavilland DH5 airplane using a 110 horsepower LeRhone engine.

Darraco is the propeller manufacturer, and many of their products for a variety of aircraft are still around as display props.

I think all of the other numbers are various inspection stamps. Most props of that era have a drawing number stamped on them, but I don't see anything that corresponds to one in those numbers you posted.

See the thread at the top of the home page here for information about posting the photos.
