I am a copier repair tech and keep a lot of the scrap aluminum that comes from copier parts. I've been taking it in for scrap. However, I am wondering if anyone would be interested in it. Some 3 1/8" pipes and 4"(just under 4 at 3-15/16") pipes. They measure about 14" in length. They have a green film on them and some may be scratched up. You could sand the film off then polish or paint it, or keep the film on. You could also wait until I get some unscratched up ones. I don't get very many 4" ones but will get about 4-8 of the 3"-1/8" ones every month. Also have 2 3/8" and 1 1/8" pipes with similar lengths. $5 plus shipping for each for the 3-1/8 or 4"? Attached are photos of the 3-1/8".Any interest? Please send PM if interested.
