Price lowered: $2,599.97 (NEW even LOWER price)
The price is now 20% lower than it started, so I'm not sure when it will find the magic number. Based on the photos, the horn is largely free of dents. I contacted seller and said he should include a photo of the pistons. The serial numbers suggests 1932-ish. Shipping is free! Given the time this has been floating around, I suggest if you want it you come up with the price you want to pay and make an offer (there is a button for that)!
