Ed's N94883, SN 5052 I show as being manufactured on 4/14/49. I have
reviewed his trim system as
depicted by FIg. 31, pages 40 and 41 of the Alon Parts Catalog.
This is the F-1A trim apparently carried forward into the Alons. The
"F" prefix of the part numbers is for
"Forney" (just as "415" preceeds ERCO part numbers). This trim system
originated with Forney Report
# F 400, E.D.R. No. 36 and Engineering Order (E.O.) 1804 in late
December of '59 and into January of '60.
It is, therefore, absolutely impossible that a Sanders 415-G completed
over ten years earlier could have
been originally built with a F-1A trim system. Forney did however, on
occasion, install "updates" to earlier
airframes.

WRB

Is it possible that this installation was factory installed when the
