I'm sure that Pierce bicycles had some tools, and that may have been one of them.....Pierce Arrow supplied tool kits with all their cars, all the way up into the 1930's. The small adjustable wrench shown was one of the three sizes that were included in those kits. There were also Pierce (with arrow through) hammers, pliers, screwdrivers, open end wrenches, large adjustable wrenches, and others....
