Now, I see one problem, the brass rings are sitting very low on the cones.So if the shifter over-shifts it will scoot those brass out to the end and the backside will pop out.
The overshifting was my original thought, but after looking closer at the ring wear I have to wonder. (didn't the syncro rings have a notch in them that those slide ring detents fit in?
And wasn't that problem caused by the syncro rings wearing and getting too far away and allowing the ring detents to move out too far like in the pictures?)
Been so long I can't remember for sure.
I'd like to see that thing on the bench in person. :-)
