I am not able to upload any of photo of my trumpet. In comparison to yours, my trumpet looks a bit like a student-trumpet and maybe a few years older. Your mechanic did a really good job, sound and looks very nice!

Hello, a few weeks ago, I bought a trumpet like yours on eBay. J.Milliens is still in Paris, today they are called Millienson and produce huntinghorns. You can find them online. Your trumpet is maybe 50 years old. I like the design and the simple sound of them, would you like to sell it? Best wishes...
