OM-1 rough film advance

[Keith]

Between 30 and 60, the slow speed governor is disengaged. Some make the sound, some don't. Some make the gear noise as you track through ALL the slow speeds. It's another thing that isn't considered a defect. To make the sound go away, remove the slow speed governor. Then you have NO slow speeds. John

Excellent ... but I'm a little hesitant to dive into things I have limited knowledge of.

John ... if I send you all my OM's for this modification do I get a discount for having them all done at once?
