Yup...


You've been lucky, Mark.

The YC pins look like a self-pealing onion, only the peal digs into the 
bushing cloth.

I got real good at removing the back action out of the bunch (7) of YC 
grands we got in the mid/late '80s.

Yeah, the hammer flanges had problems, but the irritating ones were 
those back ones.

No keepsakes, just fond memories. ;-{
