From Spartan discussion forum:

My husband and i are currently working on a 1950 Royal Mansion, she came to us gutted of all her period glory save for her stove. However we are still under her spell! We are going to outfit her in as close to original style as possible. We are trying to find somereplacement window latches for the jalousie windows. I have heard they are not a very common style,unfortunately. I have pics of some in my album titled Central Texas Royal Mansion. We need 5 sets. vtc has the arms and clips but not the other pieces. Anyone willing to part with them i’d be much obliged!
