Interlocking Three Pairs, designed by Stewart Coffin, made by Pelikan. This is listed in my notes as "Pelikan 19A", for whatever that means, and I'm not sure where that bit of info came from. The solution is interesting, though if you take it apart it will ruin it for you, so I recommend someone else disassemble it if you wish to give it a go. It has 6 pieces.There is a tiny stain on one end. Otherwise, the puzzle is very nice.

Crenal, designed by Gregory Benedetti and made by Fuller. This is a unique 6-piece burr with diagonal intersections and unusual piece play.

The puzzle was "a little loose to account for dry conditions" when made, and it's still a little loose, but functions well. See link above to original listing.
