C117 - Six Pitch Flags
"Four corner flags on bases with built-in ball raising recesses for improved corner kicks, and two halfway line flags."

These are the big orange flags with ball recesses for taking corner kicks. An alternative set of smaller flags were introduced in 1981. (C188). The old faithful flags kept going in tandem with the new for a few years, but were not given a "61" number, and were absent by 1984. On the left is the earlier version with triangular flags and a white pole.
