Posting for the first time. I just came across this one on an internet flea market. Owner said it was purchased in "86, used on a trip to Yosemity, put it in a box. Black bag has pockets, only has a flag/tag "Made in Tiwan", no "registered" mark to upper right of Matterhorn logo. There's also a Ken's price label on the Sigg, $5.65.
