Hi waikphys and all ODK member,
It's probably best that we discuss what needs to be done after you post up the photos.
I will say though that you are correct in saying that its probably not the best choice of unit as a daily driver due to the lack of parts availability. The Model 33 is not considered a later model, rather it's an earlier unit of the modern era as the Model 45 which superseded the 33 ran for over 25 years of production.
Looking forward to the photos
Cheers,
BB
