The freewheel tool looks a lot like one I use for certain old French freewheels, but which one I couldn't tell you! I had a Shimano crank puller identical to that one many years ago, purchased c.1979 or so to help service my '76 Puch Royal X that came stock with a first gen Dura-Ace crankset and BB. From what I read, the ONLY BB for that crankset is the original one. Score!
