Ron and I were recently talking about the serial numbers on Gambles Hiawatha badged bikes. So far, most start with the letters WG which stands for Waldens/Gambles then a single digit, then a 3 digit model/slash part number code. We have a theory that the single digit after the WG is possibly a date code. Does anyone else have any Hiawatha badged bikes and or serial numbers to share? Preferably from the early 60's and up please. Pleanty of pics and the complete serial number would be very helpful. Maybe we can crack these once and for all. Thank you, Kenny.
