No offence taken at all! I’m just curious to learn all I can about this particular instrument, and things that can help me with my own label identification. Before I purchased the instrument I did a bit of internet scouring about Dieudonnes, and as you mentioned is your experience, I didn’t come across any labels like the one in the instrument. I think the writing below is supposed to say “A Dieudonne”, but I remember seeing a label with his signature somewhere else, and it looked different.
Regardless, I very much enjoy the instrument - powerful with a really singing upper register and at this point I’m just appreciative of any additional information that people with way more experience than me can provide. Thanks for taking the time to look over and respond!
