Wow, that could have "sucked" way more on the Hetchins, glad it didn't take out a chainstay. 
A pleasant surprise is that the electrical tape under the front derailleur clamp served as a layer that allowed the derailleur to rotate without tearing up paint! The derailleur was able to be bent back into shape with great care, and is in use today.
The outboard spokes on the right flange of the rear hub had to be replaced, though. The chain was jammed in so tight that the spokes were badly damaged, and even the hub flange was scratched up. I had to remove the freewheel to get the chain released!

I was worried more about the paint than the steel, but there certainly were a lot of ways that the incident could have been worse.

It's funny that you ask....this discussion got me thinking about another bike that has a non-period rear derailleur - my late 70s / early 80s Ritchey road. All Campagnolo except the rear derailleur is a Deore XT. Shifts great but I'm thinking I may try something different on there.
The bike I originally posted about is a Cinelli SC that I'm building up from the frame. Most of it is Campy NR but I'm straying from the narrow freewheel.

Polished Soma Rally type Cage plates for Nuovo Record type derailleur
Spence's were a bit crude to be sure but must have worked well as he sold plenty of them I think.
Another Merz segway as he built several bikes for Spence as the touring thing ramped up with few serious options at the time.

I'd go with the Cyclone GT, for sure, and I even had the same spring failure documented above. Technologically advanced, light, elegant, beautiful.
I managed to bend a new tab on my spring to make it functional enough and eventually found in my toolbox the remains of another lower-end GT derailleur from Suntour that I bought for parts. Sure enough, it fit and worked great. As I recall, I bought it for a few dollars at a shop in Nob Hill in ABQ that moved or closed not long after!

HA! There are no old parts left in Albuquerque shops. They've all been hidden aware in the barrows of ancient collectors in the foothills. I have to wait until they die and their children liquidate.

I did buy, at the same shop, Campy sidepull brakes, a Campy headset and a 27.2 mm Campy fluted single-bolt seatpost. Also picked up my Carlton frame and fork at a bikeswap there, and some other components at an additional bikeswap a short time later.
I enjoyed it there, but never had so many flats in my life... Goatheads!

well heck, for a slightly dog-eared Cinelli SC like this stunner I reckon you should just slap one of those generic transformer-alien style Shimano Alivio units on it and go for maximum cognitive dissonance.
Also, likely that it will shift as well as any of the Deores.
Kidding aside, I vote for the Cyclone on this beastie, since it would have been a logical upgrade at some point in its life.

I say build it like Cino would have and push it up the steep stuff. Putting asian or even french parts on a Cinelli strikes me as being just plain wrong.

I'm a big fan of the Cyclone GT, but I'm just running a 13-30 cassette..
The SunTour VGT is going to shift just as well, weigh a bit more, and be more robust.
The Shimano Crane is pretty sexy too, and likely works great.
The Huret Duopar has French charm, but a weird way to attach to the dropout and a potentially fragile 2nd parallelogram. Might be the derailleur for you if you like living dangerously!
The Campagnolo Rally might be fine, but when you think touring, you don't think "Campagnolo". Never made any sense to me.

As an FYI, Greg works W-Fr afternoons, so that would be when you could catch him.

I have had the Deore XT, Duopar, and Cyclone GT on an old touring bike at one time or another. The Cyclone GT broke on a tour in France and of course, a Huret went on. Then, after many miles I upgraded to the XT in the mid or late 80's. The Huret was a good derailleur and the second best shifter after the Deore. I'd get the Huret.

well, I'm a fan of the Cyclone GT and have used them since they were new. Still, I feel compelled to mention that I've had two where the lower pivot spring has broken.
I created a thread about this on the I-Bob group, and was surprised at how many folks have suffered various types of failures.

Based on my rememberance, I think the lifetime of the original Cyclone derailleurs is adequate, however unless you know it's got low mileage on one, I'd consider that there is some risk of this happening to you.

That's what I was thinking - the Coop. Unfortunately they no longer deal in old parts. The new owners seem to be focusing on custom builds with modern parts for the college crowd. I miss talking to Greg and the other guys there about racing in the 70s/80s and searching for pulley wheels in the boneyard. Those days are gone.
