We will guess 1960's to 70's. We dont have a projecter but did put it up to a light to verify it was in color and what it was. The front reads G.R. and J.J. XXX and has a razor glued to the front. This may have been an early home made video.... This is a 5 inch reel. Given the amount of film on it there is probably around 3 to 5 minutes of movie on it.
