Anyone have one of these, or know of its vintage? When I google it, I find very little info., except that it is refered to as a "kangaroo bicycle wrench", refering to the 1800's bicycle of the same name. The picture of the bike I have posted, is reported to be the first bike to be chain driven, built in the 1860's, by the "Hillman Herbert & Cooper Company" of the same name. Any thoughts or additional info. much appreciated.
