Need id and translation for a big blunderbuss.

[asomotif]

Thank you Cerjak and Maurice
I was very happy too with this find.
The barrel was rusty when I bought it, and after a bit of cleaning the inlay became visible. Not to mention the twisted barrel structure.

here are 2 pictures of the inlay. not very unusual inlay. But in a good condition considering the age.
I will try to make some more pictures soon.

Best regards,
Willem
