Considered by many to be the best unrestored H-D Strap Tank example in the world, sporting its original paint job, engine, frame. These earliest Harley-Davidson ‘strap tank’ models are the rarest and most coveted of all Milwaukee machinery. The serial number (#2037) suggests it is the 37th Harley-Davidson built in 1907, making it their 94th machine ever built, including the two prototypes.
