Wore out three sets of tires already!
Picked this up as an oddity for a couple dollars. I was informed that it was a bicycle repair tool. It has a patent date of Aug. 1919; apparently nickeel plated at some point.Not sure how it works. A couple on ebay for $15-$30 say it is a tire repair tool. I can only assume it works like one of those car tire plug repair tools, but I can't figure out what purpose the small lever/hook piece serves. The end is forked/slotted.
