Broock:

None that I know of. They are at the edge of obscure. I only know about them because of the take-down mechanism that they employ. John Moses Browning "borrowed" the idea for his then new (circa 1906) hammerless shotgun design which he sold to Stevens Fire Arms and Machine Tool Company (he was at war with Oliver Winchester over how he was being paid by Winchester for his patents). Damnably cheeky of him. That gun became the Model 520.
