Couesnon Monopole

This is a Couesnon Monopole Cornet, serial number 16000. Unfortunately no grenade with the year as is common on most Couesnon instruments, but it still has the "94 Rue d'Angouléme" address so it must be before 1937. Based on known serial numbers and the text of the inscription, my guesstimate is 1910-1915.

It came to my home with stuck valves and some tubes stuck. It turned out valves 1 & 3 (numbered 4 & 6) were exchanged. After a thorough cleaning, pulling some tubes, putting the valves back in the correct casing and replacing the waterkey cork, it is in very good playing condition.
