Are you still looking for these? I was just going through an old box of stuff and stumbled across both the sparge arm and the phalse bottom. I would probably let go of them pretty reasonably if you are still interested.
Boy I dunno, what is it exactly? Is it in working condition etc. if you think it's a working rotating Sparge arm, I'd like it. How about 15 bucks plus shipping? You'd have to let me know how you like to handle the transaction. Thanks!
