However, the stop rod seen here is in fact a combination of parts from two different instruments. Starting in the 1950's new models, both student and professional, had adjustable third slide finger rings.įull disclosure: The main tuning slide stop rod in this picture is absolutely correct for this instrument. This is normal for Conn trumpets before the 1950's. Also notice that the third slide finger ring on this instrument is fixed, not adjustable. As far as I know this darkening of the lacquer has no effect on the sound. The dark color of the Coprion bell is due to the fact that (original) Lustre-Conn finish tends to darken somewhat with age. The coprion bell improves projection and darkens the sound somewhat. The 12B is the coprion version of the venerable 22B. Please check out the photos to see the condition of the horn.

There may be some small points of redrot developing on the tuning slide. There are various small dents and dings around the instrument, some bending at the bell bow, and some damage and creasing at the bell flare. This horn has the stylish Conn braces and long mouthpiece receiver, bottom sprung valves, and bell engraving. Valve plating is in good shape, although as with many vintage horns you may prefer to use a thicker oil like Berp No. This trumpet has fairly extensive lacquer wear, but between the aged lacquer and the patina of the raw brass portions it has an authentic vintage look.

Here's another Conn trumpet we have in the shop, the 12B! This trumpet was built around 1949-50 and features a Coprion bell.
