Vintage trombone C.G. CONN ELKHART 4H/7inch bells/narrow bore. Based on the serial number, this instrument was manufactured around 1929, and very few of these models still exist. I have used it a few times in a big band, but I didn't use it as my main instrument, so it's almost in the same condition as when I bought it. The exterior has a silver satin finish (which is quite thin), and the bell engraving is beautiful. It has been overhauled once, so there are no dents at present, but there are age-related plating剥がれ and scratches. The slide action is good, but there is age-related plating剥がれ on the skirt part of the inner slide (it doesn't affect practical use if you apply slide oil). Also, there is green corrosion on the support post on the handle side. Regarding the tone, it had a compact sound and a delicate, mellow resonance (in my personal opinion). The original hard case is included, but it has deteriorated over time, and although there are repair marks, it has become fragile, so please handle it with care (the fasteners are fine, but we recommend replacing it with another case when carrying it). I am selling it to organize my belongings. I hope that those who understand this will purchase it. *Please understand that this is a used item before purchasing. *No returns or exchanges, and you can buy it immediately without comments. *It may sell out as it is also listed on other sites. *Please do not repost the images.
