Charlie, the colonial knife fabrication stopped after WW2. Original design by pradel but many manufacturers built it also.
They are very hard to find in good condition with matching handle and blade. This is a fairly large knife.
Even reproductions are hard to get. Maybe JM has a clue.
The French flag's was inspired by US colors in 1794, it combines red for Paris, white for the king and blue for the National Guard. (France flag was red cross on white, until the 100 years war when England took it, then replaced by the white cross on blue).
There's a twin row of plane trees down my street, they have replaced the lindens of my youth. (no more helicopters!)

They were planted on sides of country roads by Napoleon for the soldiers to walk under their shadow.
There are popular all along the southern canal but got a disease killing them slowly that came during the landing in Provence with an ammunition box.
Here a once famous one in Narbonne (where my big bro' resides) defying the gendarme on the promenade called the Barques, the canal on the right!
