Dr. Sprocket (aka Rich Ostrander), recently set a couple of photos of a knucklehead he just finished for his old friend Chuck V. He didn't give any info but it looks to be a '47 with various rare sourced vintage parts.
Note the front twin leading shoe brake and at the rockers suspension dampeners. Aluminum tool box and taillight are both Crocker parts.
Hollywood bars, 18" wheels, front hub cap, 6" inch air cleaner and rectangular foot boards from the late '30's are all nice touches. I'm guessing that the pipes are vintage Superior.
Being stripped down and yet retaining so much of a Harley's vintage styling just might make Bob Jobs the best all around bikes of them all.
