Part arrived in 1 month. Tested and is working perfect. No demage and perfect condition.
A decent, playable horn, good for the price. It arrived without oil or grease, so that is your first step. My horn required some time to work in the oil. I contacted the seller for a tarnished, scratchy valve, but got nowhere. Nonchalant seller, flippant service, these go with the low price. Don't expect more than you pay for.
