I am looking to replace a certain metal hook, that is part of our windows. Where can I find a similar piece?
I live in a building that has special snowflake windows which were originally made in the early 1900s. We are not allowed to replace the windows.
Some of these windows don't close, because they're missing a metal hook. Here is a photo of the metal hook, from one of the windows that works: https://imgur.com/lTosn83.
How can I get more of these hooks? Are there particular search terms to use? If it's not possible to buy something pre-made, whats the best way to get new ones custom-made?
