Look up Hans Kerensky on flickr, http://www.flickr.com/photos/2950454...7624987139266/ and see what he did to repair a Rolleiflex (admittedly a slightly less complex model T). Seeing the 79 part story is indeed a good lesson. I sent my Automat to Jurgen Kuschnik instead.

Maybe Claus Prochnows Rollei Technical report is something to start out with.
