This is the only bike made by Harley-Davidson that had another name on the tank. It was custom built per a customers specifications. It is the Woolery Bullet and still exists today at the Wheels Through Time Museum.
The Woolery Bullet, the only name, other than Harley-Davidson, ever to be put on a gas tank from the factory. The Woolery Bullet also deviates from the norm as it has a lower frame and a vertical generator, all from the factory. A true one-off factory custom. Dale has all the documentation and photos from the Motor Company to back up this claim.
