Muntz

Does anyone know who made this violin I have? There is no tag inside. All I know is it’s old and in need of regluing. The second photo is a tracing ii made from the back. The 3rd picture has similar detail at the top and bottom. The owner doesn’t know who made it. The 4th has a similar detail in the middle and was stated as Sacquin. All these violins are assumed 19th century.

I have a violin with the same design dyed into the back of the violin. It’s old and in need of repair. That’s about all I know. Any information would be helpful.
