If you have friction-shifters, most any rear-derailleur (RD) will serve fine. What sort of shifters do you have?

any good-shifting long-cage RD should handle the 28t sprocket and wrap the chain required for your triple, IMHO. Doesn't need to be Shimano since you must be friction-only and you might find the SunTours from that era to be even crisper than the Crane GS (tho it does get major style points for the "Elvis" cage perfing).

In that you're using friction-shifters, and that Crane RD was a first-time Dura Ace, I'd say you might consider a very good modern RD. At an excellent price. These usually went for $80 - $110.

These will handle a 14 - 28T no problem.

Based on my own experience, I'll bet that Ultegra will shift much better than any vintage derailer.

The comments on the modern derailleurs shifting better are right on, but if you want to stay with something more period correct, the Suntour VGT-Luxe was at least as good as the Crane GS if not better(as unworthy1 alluded to). They are also easy to come by and usually sell pretty cheap.

A replacement Crane probably would not be that hard to find though either. I see them come up on ebay fairly regularly.
