I'll send 3 messages. Varying photos of the latch used on one side of the storm windows. The opposite side obviously will be a mirror image. I don't know if these are the original styles used since I bought the property from a slumlord and no one knows the window manufacturer. Please do your best to identify the correct or closely matched window latches and springs recommended. I will need 12 sets. I need to repair broken/missing latches within the next 3 weeks.
