"Broken ferrules were a major problem for American anglers up until the advent of fiberglass in the late 1940s. There were any number of products on the market to help a fisherman fix a loose ferrule, but a broken rod was a different story. Even great rodmakers spent a good deal of time repairing rods, and every town of any size had a resident rod repair expert who was usually kept busy. The Jiffy Ferrule was one of the last ingenious inventions of this kind, invented by Lou DeWolfe and sold by A.F. Driscoll Co. of Denver, Colorado beginning in 1949. Jiffy Ferrules were short aluminum tubes that went over the break in the rod and locked in place with screw-in ends and offered an angler the opportunity to continue fishing instead of going home. They came in sets of three (all different diameters) and sold for $1.55 postpaid. Had they come along a decade earlier, they would probably have been a big hit. However, fiberglass ended the dominance of bamboo rods and the need to repair them, so they did not last long on the market. Your ferrule set is worth $10-$20 if complete in the package.
