We have a family of these latches which came out of a pantry of an old house here in Kansas. We have priced them individually. The cast iron has been cleaned and the small white porcelain knob wiped clean of the old dirt.,The era of this latch is around 1880s to 1910. The body of the latch measures 1 7/8 inches by 1 1/4 inches. With the keeper the entire length of the latch is 3 inches. This latch works by one sliding the knob back and forth to control the plunger. The latch is spring loaded and works well. Black flat-headed screws will be included.
