So, I just got my new jetpack from FS and needed some parts. And guess what came on ebay? A sweep arm! The best part from the auction "It's in excellent condition, all the adjusters work smoothly and there's plenty of life in the brush - I believe that's genuine squirrel hair." Squirrel hair?!?! I see them all the time and never thought to myself, their tail would clean my albums like nothing else! No I will not be trooping with the real part on my jetpack. It will most likley be a cold cast copy.
