Dating Courtois Cornet...

[barliman2001]

Yes, I know, Courtois and dating don't go well together...
but I just got a Courtois cornet from Ukrainian dealer Igor Igor (three concentric cardboard boxes and then the original case, well protected with bubble wrap inside). Condition almost as new. Serial # is 72xx, has the name Gustave Murset engraved on bell.
Probably 1950s or 1960s - but can't date. Anyone out there who might be able to help? Info on Gustave Murset also welcome.

@barliman2001 Additional info: Original mouthpiece is quite sweet, but very very narrow in the shaft... other cornet mouthpieces don't fit...

STILL WAITING FOR FEEDBACK

I am sorry I cannot help in anything but speculation and I am sure that you already have any information I can turn up however as nobody else has answered I will do what I can.

This

https://www.brasshistory.net/Courtois-Trumpets.pdf

shows some history and might place your instrument after the balanced model

I am going to add this site which is of no value in dating your instrument but adds flesh to the bone on courtois early history and may be of value and interest in showing some of the early history leading up to your instrument

https://www.robbstewart.com/courtois-early-modern-trumpets#:~:text=Early Modern Trumpets by Courtois The history of,glean from a few early modern Courtois trumpets.

The two sites together show courtois history and quality in design

Hornucopia shows some hostory but nothing on Gustave Murset which is disappointing, however as you know it is usual to have instruments carrying unexplained and unique identifiers that cannot be identified in any history and trying to date using engraving details can be a nightmare and fruitless.

Hornucopia shows these serials that place it in the late 50's

This is an alternative history

Again nothing on Gustave Murset

In conclusion I have nothing useful beyond your instrument appears to be dated possibly around the 50's as you already stated.

The serious lack of information available suggests that anything we have seen may be wildly inaccurate.
