I recently purchased Mark's collection of books, pictures, advice about the typical German movements and their manufacturers. He calls it The Project, and it is an amazing collection of materials to aid the repairmen of these movements, even including the Hermle Repair Manual. He charges less than $30 for the whole digital collection and it's a steal at that price. Here are some of the things you get: Inside each file are detailed photo's of and exploded pictures of the movements made by each Manufacturer. It's a great asset to newbies and experienced repairmen alike! Edit: I tried to include a screenshot, but the MB is having difficulties. I will add it later Edit: Trying again - nope, no joy.
