need help

Thanks so much for reaching out to us. I can tell you right off the bat that this is a very old clip. I've never seen this exact style before, but I can tell just by looking at the design of the window.

So, to cut to the quick, we don't sell this exact clip. Your best hope is going to be to find a modern alternative. That's going to depend entirely on size, though, and I don't know the size of yours.

The most pertinent dimension here is the offset. Can you give that to me? In the meantime, see our full selection of plastic clips here and metal clips here. I can't guarantee we have something that can work, but you don't really have any option but to try to make one work.
