The Falmouth address isn't a "real" Gibbs. A mail order place on Dillingham Road called The Tackle Box owned Gibbs for a year or two in the early 80s, before John Gibbs reaquired it from them. I'm not saying there's anything wrong with them. But they come from a period when Gibbs wasn't family owned, which might affect their value with purists. As a fishing lure, they're fine.
Imagine The Surfcaster with a retail showroom, and you have The Tackle Box--I miss the place
