Just bought a 1977 Super LeTour 12.2 (the full chrome version) with downtube shifters:




Everything else on it but the saddle and bar tape seems pretty original. If I wanted to return to downtube shifters, any idea what would be correct?

I was thinking of the earliest 600 lever I could find (since 50% of the bike was running 600), but the catalog looks like some rubber-tipped lever or another.

I know early 600 did, in fact, offer a bar-end option, but I don't think that was it. Plus, I just like downtubes.
