This olive drab (OD) Canon F-1 was made available for a limited run of somewhere between 2000 and 3000 bodies. I contacted Canon Japan and they claimed that these were made available starting January of 1978. According to them there were 1000 made available in Japan and a total run of 2002 units, though they did say they were unable to comment on Canon matters outside of Japan. As such there is little certainty on whether or not these were sold in a separate run in the United States. Certainly Canon Europe appears to believe that they were only sold in Japan.
