-JdK- Leon in Australia is struggling to find a double acting oil pump or some of the associated parts for his Model 25 project, he has the remains of the original pump that snapped the driving shaft.
"I’m hoping there is a second hand one out there somewhere that someone is willing to sell; I managed to borrow one from a generous model 25 oner over here for a short time who is refurbishing their bike and that is what the photo’s are from. So either from both Norton Model 21, Model 25 are the same and I think early Carroll CS1 oil pumps would also be suitable.
If anyone got a spare Oil pump or some parts of the pump from any of these models that they would be willing to sell please contact this website."
