What was an alternative name used for the 7 Iron golf club during the early 20th century?

Early golf clubs were all made of wood. They were hand-crafted, often by the players themselves, and had no standard shape or form. As the sport of golf developed, a standard set of clubs began to take shape, with different clubs being fashioned to perform different tasks and hit various types of shot. Later, as more malleable iron became widely used for shorter-range clubs, an even wider variety of clubs became available.

The names used for early 20th century wood-shafted irons were:

Driving iron: 1 Iron

Mid-iron: 2 Iron

Mid-mashie: 3 Iron

Mashie iron: 4 Iron

Mashie: 5 Iron

Spade mashie: 6 Iron

Mashie niblick: 7 Iron

Pitching niblick: 8 Iron

Niblick: 9 Iron

Jigger: Very low lofted iron, shortened shaft - similar to a modern chipper

From 1924 golf clubs started to be manufactured with shafts of steel, pyratone, aluminum, and fiberglass or resin; many of them were given a wood-look coating.
