Okay guys thanks for all the help. Couple of things.
1. Only one part is really rusted (the piece that screws into the bottom of the stem). Lemon Juice should cover the rest
2. I have a tetanus shot, so I don't have to worry about that.
3. I live in probably the most liberal part of the country, (Boston, MA) which means there aren't any gunshops that I have ever seen lol. (I have never even held a gun :0)
4. Are there any homemade techniques for cleaning the interior? (A toothbrush maybe?)
And thanks for the advice, it has been really helpful.
p.s. I will try to upload some pics tomorrow when the sun is out because my lamp makes it very hard to see.
