1960s Brinko hand drill - Donated by Matthias Hofle
1960s piton bolts donated by Matthias Hofle. The bottom piton bolt is different from the other four. The bottom piton bolt has a 90 degree "angle stem to piton carabiner housing side" and also does not have a extended end for the hammer to hit against.
