I live in a Victorian-era house in Philadelphia. We have a double hung door into the kitchen and one of the hinges has completely given way. I need to find replacements but I'm having some problems finding the right replacement. Here is a photo of the original hinge, and there are more online:
It appears that newer hinges have a slightly different design. Notice how the original folds compared to the one I linked to.
The door I'm hanging is about 1 1/4" thick.
