Thank you for the help.
The # you mentioned for the odometer is correct. It does say MB# 1235422757 on the face. However the brass gear on this one has 18 teeth.
I think I need to re-name this thread "Cluster Bomb"! I'm pretty close to lighting the fuse.
What do you think? Someone did a swap?
If I know that a 15 tooth brass gear will fix the problem... I will order it. I just need to know.
Here is what I got. Sorry for the bad pictures. It is late and I am tired:
