I am trying to find out if a frame stamped CB31-9860 is a 1954 goldie frame as the seller is telling me. Goldie CB31 frame numbers from this year started at 101 and I am doubtful if they made 9000+ in one year. Frames for a 1955 B31 were also stamped CB31 but they started at 6001 which seems more likely and they are not made of the same metal. does anyone have records of frame numbers or any suggestions. Thanks, Neil in oz.
