Bert,

I see a standard model 64 in .219 Zipper coming up in a local auction.  Serial # 1122531, bolt peep, drilled and tapped for receiver sight, appears to be a 26″ barrel per listing photo.  Is this new to your survey?

Yes it is.  Interestingly, I have serial numbers 1122530 and 1122532 in the survey, both 219 Zippers.  Can you send me a link to the auction listing for number 1122531?
