Ah! Nice. Yours has the earlier style shifter. I much prefer these. 62 is a close call for the change. These have embossed, chrome plated brass face plates that were such a nice detail. You never see this kind of work on a bicycle anymore.These also have the threaded ferrules which make a more solid connection to the cable housing. Instead of the later ball and keyhole connection. This ferrule has a threaded stem that screws into a threaded hole in the shifter case. There;s a blank spot on the stem so when you screw it in all the way, it will come to the blank spot and spin freely, but the threaded section will keep it from backing out. To remove it, you pull back on the ferrule and turn it until the threads engage and it will back out.
