    My first Bb trumpet was a Couesnon Lafayette trumpet (made in France) that my Dad grew up with. I still have it and play it in certain settings. To me, it seems to have a smaller bore when I compare it to a ML trumpet and works really well for really technical pieces.
    I would love to know what the bore size is. I can't find anything anywhere about bore sizes on these trumpets. It has a VERY small D stamped on the 2nd valve casing, "K" stamped on one side of the reciever and "D20" stamped on the other side. Actually the" D20" my be "P20." If that's the case, someone had mentioned that the "P" may mean petite for small bore. Then what would the "D" stamped on the 2nd valve casing mean? What would the numerical value of the bore be?
    Thanks for your well....chad

    my own first trumpet is a Couesnon, 105 rue Lafayette Paris in C/Bb.
    I assume that the Lafayette brand was created specially for the US market because, in France, we do not know this brand, only Couesnon (with an address) or the Couesnon Monopole name (the top of the line).
    Regarding the letters, I made some studies about this, regarding the Monopole Flugelhorn and posted the results on TH (topic "Couesnon Flugelhorns").
    As far as I know, there is no relation between letters on the horn and any characteristics of the horn. It is only the first letter of the name of the guy who was responsible of the valves or the leadpipe, and so on...

    As I recall, Kenny Dorham endorsed this horn.

    Pull the 2nd valve slide and find someone with a set of calipers to measure the inside diameter. The machinist who does the work for your auto parts store can probably measure it for you.
