Devon Minnow are hard to come by these days even in Devon. The earlier ones were something like an oversized spin and glow. The bodies were of painted wood. It spun on a central hole with plastic spinning wings and usually was equipt with a small triple hook.
They were fished for trout and sea trout.Later they were made in sinking models of cast metal. Usually they were fished from a centerpin reel since the Brits hated baitcaster reels. " sounds like a model T ford dont you know"
