I purchased this original Road Master for our give away bike for 2017 at the Get A Grip Bicycle Show in Cleveland TN. We give away a bike each year and will be keeping this one by our side this year as we advertise the show for the fourth Saturday in March of 2017. It has cleaned up very nice and will help if I know the year model this was produced. Based on the fenders I am guessing 1939-1940? The serial number below the crank reads D10985. I appreciate any help on this bike and thanks for looking.
