I have had a trumpet sitting in the basement for several years now and decided to bring it upstairs for a look.  Engrave into it is Made By C.G. Conn Elkhart Ind. USA.  I have tried to google it but can't seem to find anything with the exact serial number, at least what I think the serial number is.  The only number I can find is 270307.  I plan on polishing it up and displaying it and just wanted a little more info on it.  Thank you for your time and help.

Your Conn trumpet was made in 1929. Depending on condition and completeness of case and accessories, it could be worth some money, though you won't get rich from it. Some of the older models, such as the 22-B, are desired even today.

The excellent Conn Loyalist site,, will help you to identify your trumpet and tell you more about it.

As for polishing, use the mildest polish you can find. Most players with silver horns use Tarni-Shield for polishing. If there is any gold plating, be extra careful with it, as it is very thin and comes off easily.

I can answer your questions about Buescher trumpets and cornets. I have been playing Buescher for 35 years and collecting for 7.


I first started playing my grandfather's Buescher 400 trumpet in 1975. Since then I have done a lot of research, including original catalogs and advertisements that I own, correspondence with other Buescher owners, and obtaining my own Buescher collection, including six trumpets and three cornets.

I am a technical writer with 15 years experience. I have also been playing trumpet since 1975 and collecting Buescher for the past 7 years.
