hi all, this is my first post here. great site. i picked up 3, what look like newhouse trap clamps, in the # 4 size i believe. they measure 6 1/4 inches from the top of the frame to the bottom. i thought the #4's were marked with a 4 in the top collar. i dont see any markings on them. i was wondering if these are original newhouse clamps or repo's. i picked these up at the late leo hoeft auction this past fall,near ladysmith wisc. if they were original, what would they be worth. thanks randy

Randy, Your clamps are #5 size, the #4 size is 3 1/4 inches and #6 size is 8 inches. These do look to be Newhouse, The early clamps are marked with a size # but not the later oval and round top clamps.
