I believe the part that broke off is a cast metal of sorts with a brass or bronze plating. It is slightly magnetic, so I assume there must be nickel in there. Would some sort of epoxy hold this together, or does it need brazing?
Bought it at a book fair years ago for £10. It is signed by the artist Tanya Roberts, who is the illustrator of the book. I don't know if she is well-known or not in this community, so can anyone suggest how I may sell this or perhaps give me an estimate of its value? I also have a one-off illustration she did of Monkey D. Luffy that I am willing to sell.
Kind of looks like a gun.
