Chouinard Lost Arrow pitons
Chouinard Thick Horizontal piton
c.1959
I have seen a few others of this piton. Since it appears to be not so well crafted, I consider it a junk piton. Maybe it wasn't coming out correct so it was thrown to the side.

Chouinard horizontal pitons
c. late 1950s
What I love about these pitons, which the yellow paint brings out wonderfully, is the circular scrape mark around the piton eyes. In the Dolt 1960 catalog photos, the scrape mark can be seen on image #202.
