Not Beethoven - but it is from that early romantic period. Sounds like it could be from an opera by Mehul such as 'La Chasse de Jeune Henri' which I've seen on a similar overture box by Ducommun Girod.
@@ptmusicalboxes Well rack your brains Peter & let me know when you can place it, the owner has being trying for decades. I’m sure you will agree it’s a fantastic box, my vid doesn’t do it any justice, it’s really up there 😉
