This is an exceptional pre-1900 Victorian window latch. Finding this elusive piece of hardware is challenging because most of the time the keeper is missing or the long arm is broken. Currently we have only one.
The latch part, that mounts on the inside window sash, measures 2 1/2 inches long and 3/4 inch wide. The hole centers are 1 1/2 inches apart. The arm that swings from this part is 2 inches long. It is topped by two bronze coated finials. The arm has as hook that fastens into the keeper. The keeper, that is on the outside sash, is 1 7/8 inches long and one inch wide. Across the backside of the keeper is a corrugated-like surface for the swing-arm hook to rest.
This is a fancy cast-iron piece that is well over 100 years old. We will include the proper screws.
