Wow when a community comes together! The old casting 335 instruction book is just what I needed. My machine looks like that.
I am going to download and print it. Thanks all. My 335 is relatively new and totally clean and usable. The new addition 29K-51 shoepatcher from july 1925!! will need some cleaning although everything works. There is a lot of old filth inside. It just needs a good clean I think. I bought WD-40, strong degreaser, rags, cotton sticks and cola. Hope that will help. I will be making a lot of pictures in order to reassemble the whole thing. I love ikea projects but I have never undertaken such a project.
As a kid I loved technical lego and not dolls. I have pictures of me in a pink dress with a big race car in my arms. My whole 36 years I always was busy with some project either sewing, embroidering, lego, leather, fixing up things etc.
