My friend was able to get a set from a person in my town that worked with Carroll Shelby. Any guess on value?
Good shape. My friend is not ready to let them go. Has there ever been a set for sale in the past?
New original Cobra or new original 427 Cobra, makes a difference. Sold as service replacement or new car version(s)?
Yes, used original production sets marked 1963-64 for Cobras have been for sale before and original production sets for 427 Cobras used and new old stock have been for sale before.
In all cases the public offerings were so far apart in years I would not imagine what a "market" valve currently might be. Originality plus condition would be the key factors in my opinion. Car owners have tracked down used sets for specific cars for decades and except in my case, I have no idea what pricing was in private sales.
