replacement latches / lock for approx 50 yr old casement windows

I hate to say it, but I don't think we will. This looks incredibly old. I can tell you right off the bat we don't have a lock that looks or works exactly like this. We have a couple that are similar, but they're so different that I don't know if they will work. You can see our entire selection here to get an idea of what we have. Sorry we couldn't offer anything better.
