Hello, I'm looking for issues 15, 20, 28 and 30 of Metal Forces magazine. Don't need to be in"mint" condition, but would prefer they be fully intact. I would prefer to buy, but I have a few doubles of certain issues that I could trade also. If you have any, that you would consider parting with, please get in touch! I'm also looking for certain other issues, so feel free to let me know what you have. Btw, I'm in the U.S.
