Digging a new flower bed in the back of our 82-year-old apartment building, we found ourselves unearthing a very old small landfill with all sorts of interesting items.
Among them is what appears to be a toy pistol, or possibly even a real pistol. But it is totally covered with heavy, heavy mud and rust.
I boiled this in salt, then salt and vinegar, but nothing gets it off.
Any ideas welcome.
