Mills,
Before you go too far with repairs ou might want to figure out its value. The repairs however small are likely to exceed te gun's value.
There are only 2 Richards guns that hold significant value . The ancient firm of W. Richards of Liverpool (who never marked a gun with any London address) and the newer firm of Westley Richards of London.
Numerous Belgian and American guns played on the goodwill and quality of those two firms with the intent to deceive. Probably the single most plagiarized name in all of guns is "Richards".
I'd love to see pictures of your gun when you get a chance.
