There is a full page color ad for the Spring Rat on p. 139 of the Nov/Dec 1976 issue of BASSMASTER. It came in 1/8, 1/4, and 3/8 oz. sizes. Rogers Lures address at the time was Purdy, MO.Yes, it was called the Spring Rat, by Rogers Lure Company, Lamar, Missouri. Rogers in now in Liberty. Maybe they have stores elsewhere? I bought one in the late 70's or early 80's.
