Sidelock + KRUPP + "Knock About" + Dolls Head = Sauer

Boxlock + "Knockabout" = Francotte (I have yet to see a Fran with KRUPP bbls)

Cameron...I am collecting serial numbers on the Sauer Knock Abouts for my on-going Sauer research. If you could please make note of this ones and relay it to me I would be very grateful. Please send to sauercollector@hotmail.com

Danke and best regards, Jeff
