pw7351,

What's all that crap on the front end?

I have one I have been kept in my Winchester parts bin also. On top of the lug is an irregular shaped oval with a punch mark in the middle. Only other marking is another punch mark on top. No normal code letters.

I'm sure it is not from Taipei as I have had it 20-25 years. Just didn't know if I should really put it in a Winchester or not.
