Book says that serial number was manufactured in 1937 but the numbers in that range (22514-BD to 52636-BD) only had BD at the end. The BDO suffix shows in the same year in the 40346-BDO to 52630-BDO range. There was an overlap of numbers in that range that had both suffixes but it's not showing any BDO's as far back as your number. I have no idea what the suffix letters stand for. Maybe someone else on here does (Jack?).........GB
