Czech Patent # 116,453 - Favorit

Czech Patent 116,453 - Favorit PWB main image

This patent appears to be for the cunning device that limits the rotation at the rear knuckle of the Favorit PWB. While that may not be earth-shatteringly interesting, this patent does put a date on the Favorit PWB (which is shown as fully complete in every detail) and also names its designer; Václav Silovský.
