Trumpet/Brua C Keefer Coronet


I have a Brua C Keefer Coronet. Mfg in Williamsport PA. It is an American Model Maker 5039. The only marking on valve casing is 'K'.

I would like to know when it was made and what it's value might be if considered in good condition.

Thank you

We'll have to assume that your Keefer cornet's serial number is 5039. If so, it was made about 1915.

Value on old cornets is not high.  You might get $100 for it. You might not. To get real interest, it would need to look nearly new with all of its case, accessories, and so forth.

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.
