Stromberg Wiper Motor Repair?

[V16]

I have always been fascinated with these beautifully made early Stromberg wiper motors but have never been able to find one in excellent condition so as to make it operational. Well, I found one and I am reluctant to dig into it with out first knowing a little bit about what is inside so as not to create more problems than I can fix. Does anyone have a knowledge of how these come apart and how best to lubricate and service the internals? Thanks for any help, Allen
