I believe the house was built in 1977. I need replacements for several which have broken. Please advise. Can you tell me where to begin to look for them? or a brand or anything?

Hello. We do have a selection of similar tilt hardware for storm windows, which you can view here. I've related a few that appears to be similar to your original to get you started but you'll need to carefully compare the dimensions on our product pages to your hardware to see if one of these will work for you. Thank you!
