Up for auction is a 1924 Conn 24B "Opera Grand" trumpet (serial number 215768). In spite of the name of the horn (Opera Grand) this horn was intended to sizzle in a small jazz combo situation. Here is what Conn said in their catalog at the time:

This model is built with a small bore and is known as the 24B. It was built especially for "jazz" or ball-room orchestras, and has proven its value for this character of music most successfully. It possesses a stinging, yet musical quality of tone and unusual carrying power. From the time this trumpet was placed on the market, it met with success and swept all other "jazz" behind it. It is extremely easy playing and is particularly noted for this feature. We do not recommend the Opera Grand for symphonic or concert engagements.

This horn is has its original satin finish. The slides and knuckles of the horn are yellow brass, while the valve casings are copper and the bell is made from bell bronze. The valve caps and finger buttons appear to be gold plated,  but I can't tell for certain. The bore of the horn is .438" (Conn #1 bore). The bell is 4 1/2". The engraving is in good shape, and reads "Made-By/ C G Conn Ltd/ Elkhart-IND/ USA". This horn looks beautiful and plays very well. The valves have good compression and the slides all move. As for the aesthetic condition of the horn, there are a few small dings and some light rippling. One of the pearls in a bottom valve cap is also cracked. All this is visible in the pictures, and none of it affects the playability of the horn.  This instrument has been professionally cleaned in our shop and repaired to full playability. This horn is not lacquered; therefore fingerprints should be wiped off after use if the player wishes for the horn to stay as shiny as it is now--if they are not wiped off then the horn will develop a lovely patina. This trumpet comes with both its normal tuning slide with the "pull to A" rod, and an additional Bb/A change valve tuning slide. It also comes with two original "Famous Artist" Conn mouthpieces-- a Conn BI-230 (conn no.4) and a Conn BI-222 (conn no.7) in worn condition, and its original worn case.
