This is a Fullerton Olds Ambassador that was overhauled by Tuck Music Store and then converted to a C Trumpet. After that, I send it to Mr. George Rawlins for "tweaking". This horn sounds great! Please check out Tuck's website. He does a lot of trumpet/cornet repairs or overhaul. Sometimes they sell here on ebay too.Also check out George Rawlin's website or his facebook. He goes a lot of "tweaking" for trumpets and cornets.The 1st slide was reversed so that a thumb hook can be added. The 3rd was also reversed. Check out the original third slide stop! The original case and an Olds 7c mouthpiece are included. I'm also including a Leather Specialist Co. valve guard modified in order to fit.
