The first lure I have seen from Smithwick using this blank was stamped "My Pet". It was from the late 1950's. During the same time period they used this blank with a flat belly and it was called a "Scooter". This Scooter was produced to a least 1960 and perhaps for a few more years. The earliest chart I have on the Buck & Bawl Jr. is 1963 and it has one spinner on the rear. It shows up like this again in: 1965,late 1960's. By 1972 it is shown with spinners on both front and rear and stays this way into the 1990's. from the 1977 chart to the 1990's we have the F-1100 Buck & Bawl Jr. with two spinners and the A-900 lure with one spinner called the Scooter although the lure itself is stamped Buck & Bawl Jr. I do not have any of the charts for the 1973, 1974, 1975, 1976. So the Scooter using the Buck & Bawl body with one spinner may have emerged sooner than 1977. This lure is in the shrink wrap box and comes in color #4 Green Minnow.
