I am in need of a gearbox from a Douglas opposed twin, probably from the 50's would do. If you have one or know of someone who does, I would appreciate hearing from you. I could even use a slightly damaged case as I can make repairs. I am building a vintage looking motorcycle using a Crosley 4 cylinder for power (16 horsepower) and feel that the Douglas style of gearbox would be what I could use. Thanks for your help..........Harry
