As far as individual guns go, Of the original Armalite Hollywood prototypes, S/N 1 and 2 definitely had the top handle, but S/N 4 had the charging handle in the typical location.
S/N 1 was much more similar to the early AR-10's than any other AR15 ever built. S/N 4 is essentially the design that went into production.
S/N 1
S/N 1 is 2nd from top, S/N 4 is 3rd from top.
Cool
I still like my Garands better....but cool..
