Storm Window Hangers Hardware vintage antique old used

Looking for old storm window hangers as shown in the photo or an older design - late 1800s. There would be 2 pair of these per each avg sized window (4 pieces total).

**I do not care if they still have paint on them or if the screws are missing. I want them to be in working condition - not bent or broken.**

Need at least 36 2-pair sets plus 2 extra females (bottom) pieces.

Photo is reproduction hardware and only shows the left side pieces (looking at the window from the outside).
