Wounded Spook, a transitional one?

Today, I received a Wounded Spook in silver shore color. Looks different from other ones? Yes, it has silver scales on the back and belly. It must be one of the transitional Wounded Spooks made during 1970-1971, when the painting method of eyes (black pupils) were changed from hand-stumping to air-spraying. These lures are often called "one-year Heddons" and I haven't seen many of them.
