Abel - congratulations on your new website - it looks great and I can tell it was a lot of work. Hope you can keep up with it, its hard to do.
I have been meaning to ask if there is some detailed published info on the movement differences (gear teeth, etc?) between the cal 11 vs 12 beyond just the balance speed. I have ran into more than one 11 or 12 with mixed parts installed and I bet you have too? Craig
