Hi Barry, I think you will find the Model 45 easier to work on, I have had one for years and the good thing is all parts are still available.... they were the most popular model that Scott Bonnar made...so much so, that after Rover took over SB, they kept it in production badge engineered as the Rover 45.
There are manuals and parts list in the Manuals area on this forum.
Can you please post some pics of your new machine?
