I use conservators wax from Lee Valley, many use renaissance or ren wax. I don’t always wax though, I often use VCI paper for stuff that I and storing, and VCI emitters in my displays.

That is what was said, however I don’t think that was the spirit. Some preservation is required. I think you should do some small but simple thing. Scraping off the active rust, maybe a light hand...

That is a beautiful pile of entertainment.
