#1 is a Bosse pencil holder from his German period, repurposed by gluing in a worm. It fails the usability test, not to mention the obvious glue.

#2 is a copy of the Hagenauer fighting cocks corkscrew. It fails the marks test, as it is marked on the side rather than the bottom, it also fails the weight and finish test.

#3 is a Rohac owl figurine with a worm added. It fails the usability test.
