The bell diameter measures 4.58. The horn features a 1st valve Taylor Phat thumb ring. The slide was modified to allow intonation adjustment. Taylor Phat 3rd valve slide and pinky finger rings added for a more modern eclectic look. All the old lacquer was removed. What few small dings the horn had were gently removed. The instrument has been chem cleaned and thoroughly cleaned inside and out. The horn was then re-lacquered utilizing a clear baked-on epoxy lacquer. The satin to glossy finish is not perfect. Some slight signs of last step buffing swirls somewhat noticeable here and there please see pictures. The pictures of the instrument taken apart are pre re-lacquering shotsno corks in waterkeys etc. This horn has that big warm volume of sound which is unusual for a smaller bore size instrument.

The 1st valve thumb ring and the 3rd valve finger ring adjustment move freely without drag. Excellent valve speed and compression. The bottom sprung “Conn Crysteel Clickless” valves look, feel, operate just like the infamous Conn Vocabell model trumpets of roughly the same era. Please do your personal research, as you should, on this fine brand/model of hard to find anywhere instrument. I’ve provided some valuable information below that may get you started. The information came from the Conn Loyalist and contains much useful information for most of the vintage Conn line of trumpets and cornets. A few pro player websites yields many useful insights into pro players regards for the model as well, check it out. The Conn 7C mouthpiece is in good condition. The case is non original(Yamaha leather double trumpet pro gig case with carrying strap). It is close to new condition. The instrument and case have been cleaned inside and out and sanitized/disinfected with a hospital grade solution(Cavicide). An Ultra Pure Oils Deluxe Trumpet Care Kit and a 4oz. Bottle of lacquer polish will also be included(see pictures of case and accessories). The horn will be clean, shiny, sanitized, valves oiled, slides lubricated and ready to play right out of the box. Feel free to ask questions. Excerps below from The Conn Loyalist info re Coprion 12B: (Thank you Conn Loyalist). This period saw many musicians who played at a professional level. As a result and as far I can tell, almost all Conn instruments produced under the C. Conn brand were professional level instruments. The differences between the models were mostly related to features with models tailored to orchestral playing, jazz, etc. Also some preferred large bores, others smaller bores. Some models might have possessed additional features making them slightly more expensive, but as far as I know there were no “student” models produced under the C. Instrument owned by Christine Derksen. Notice the Coprion bell. The 12B is the coprion version of the venerable 22B. The coprion bell improves projection and darkens the sound somewhat. The dark color of the Coprion bell is due to the fact that (original) Lustre-Conn finish tends to darken somewhat with age. As far as I know this darkening of the lacquer has no effect on the sound. Also notice that the third slide finger ring on this instrument is fixed, not adjustable. This is normal for Conn trumpets before the 1950’s. Starting in the 1950’s new models, both student and professional, had adjustable third slide finger rings. Full disclosure: The main tuning slide stop rod in this picture is absolutely correct for this instrument. However, the stop rod seen here is in fact a combination of parts from two different instruments. When it first came out the 12B was apparently featured by the entire trumpet section of the Jimmy Lunceford orchestra. I also read that Bunny Berigan used it for the sound track of the 1942 movie “Syncopation”. There is a question as to the year in which production of the 12B started. The Conn trumpet model number index on R. Jones’ website indicates 1938. Conn documentation says the Coprion process was invented in 1938. I have come into possession of a Conn trumpets and cornets brochure dated April 1938; it doesn’t list the 12B. All this suggests a start date for the 12B of 1938. Nevertheless, 12B’s with a 1937 serial number appear regularly. I have developed the following theory about that: Conn, in my experience, had the habit of producing large numbers of a new model during the year in which it first became available for example: ever notice how many of the 10B Victors you see around are 1956 models? Since the 12B is essentially a 22B New York Symphony with a Coprion bell, it isn’t unreasonable to assume that in 1938 Conn used partially assembled 22B’s it had, with 1937 serial numbers, and added a Coprion bell to make a 12B. It would be interesting to see if these 1937 12B’s have “2 2 B” stamped underneath the mouthpiece receiver, which would confirm this theory. If true, this might also explain why the Conn trumpet model number index on R. Jones’ website incorrectly lists the 12B as the “New York Symphony”. In 1955 Conn gave the 12B Coprion the same treatment as the 22B New York Symphony, renamed the 22B Victor. However, while the 22B was produced for many years after 1955 in only slightly changed form, the 1955 12B was dropped after 1955 in favor of the 10B Victor. What Conn said in 1939: Built in small bore, but the seamless bell of Coprion gives it the power you would expect only from larger bore. Ease of playing, beauty of tone, accuracy of scale and amazing flexibility. Impossible to overblow or crack a note. Patented Clickless Crysteel valves. Brass, heavily clear lacquered. What does Coprion do to the sound and the way the instrument plays? It is said that on an instrument with a Coprion bell you can’t overblow or’crack’ a note. ” Also, according to Conn, “Coprion has a special characteristic which permits great dynamic range without change in tone color. ” It is generally accepted that high(er) copper content bells make the sound “darker and have better projection. Jeff Stockham puts it well describing his 1959 10B Victor: The copper bell also adds projection. This has been borne out by acoustical experiments done by Walter Lawson on french horn bells and by Cliff Blackburn on trumpet bells. Simply put, the high-copper-content bells direct a greater percentage of the energy expended by the player towards the audience, as measured in decibels. The sound of the instrument is less full behind the horn, to the player’s ear, but it is richer and louder in front of the horn — there is significantly increased directional projection. What this means to the player is this: 1 you need to exert less effort to produce a given perceived volume at any point in the performance hall, and 2 the sound remains darker and fuller without becoming shrill or breaking up at high volume levels. So with this 10B I can peel paint off the back wall of the hall if I feel like it, or blow a soaring solo line WITHOUT A MICROPHONE over the top of a screaming big band and still be heard. The limited experience I have myself with Coprion bell instruments confirms this: it projects like nothing else, the sound doesn’t break up or become shrill at high volumes and you can really produce a lot of sound, and the tone color stays more or less the same no matter how loud you play. Which instruments have a Coprion bell? 12A Coprion, 10A Victor, 28A Connstellation (through serial number 9xx, xxx), 38A Connstellation short model (through serial number 9xx, xxx; beware that there was a 37A Connstellation short model with brass bell), 18A Director and 17A Director. 12B Coprion, 10B Victor, 38B Connstellation (through serial number 9xx, xxx) 18B Director, 17B Director.
