There were two that did not succeed. One was the Whitney Wolverine automatic pistol, a streamlined .22 rimfire 10-shot that looks modern even today. It was made from 1956–1957 and only 13,000 were produced, despite its very reasonable price and the fact that it was a very good gun. The Wolverine had an investment-cast aluminum frame, and was likely the first American-made firearm to utilize this technique. Today, a re-created Whitney is made by Olympic Arms, but if you'd like one of the originals in really nice shape, the price is over $1,000, which is a bit more than the original $39.95.
