Hi Steve. As you can see I've just started posting on here. I'm not sure if the Harley's were popular with the RAF.....Or just forced on them Ha Ha!..... Like the 741's, I don't think they were well liked by the front line boys and therefore issued to the RAF and lower echelon units. Mind you, they are fun when you get used to them. As I always tell myself, when I go for a wobble on my 741. Ron
