Storm window hinges

Does anyone have a good source for window hinges? My house has two removable casement storm windows, and one of the hinges vanished over the summer (I’m picturing tiny elves with screwdrivers…)

The hinges are posts that attach to the wall - the half that attaches to the window is a large eyelet.

Here’s a photo of what I’m talking about.

Anyone know where I can find these? Or what I can use as a replacement? The local hardware guys have no idea.

Your photo has stuck with me, who sees that kind of storm window anymore? Truly an original!

links of suppliers of windows, doors, period hardwardware and shutters. This merchant was on that list I bet he could help.

Im bookmarking that motherlink!
