Thanks for the responses, I was talking about the quill bolt (which I call the binder bolt) as opposed to the handle bar clamp bolt (which I usually refer to as just that or the clamp bolt)... I guess it would seem more likely that the later 1R stems I have had (2) had the quill bolt replaced due to stripping if all the 1Rs had alloy bolts. They are nice to look at but as mentioned you really have to crank that clamp bolt.

The Cinelli 1R was my stem of preference until the late-1980s, and every one I've seen had an aluminum binder bolt. Only problem I ever had with the aluminum bolt was stripping the threads - never broke one. 1R stems were fairly common around 1980, but had problems with the internal handlebar clamp - tended to break if tightened too much, and with the additional leverage of long time trial bars the clamp just couldn't hold bars tight enough. Pretty design, but not entirely successful.
