Help IDing a muzzleloading Shotgun

[gravyboat]

Can anyone help identify this old muzzle loading shotgun?

 

[tiriaq]

It would appear to be a plain single shot shotgun of a type manufactured in large numbers in the 19th century. Missing the rib under the barrel which carried the ramrod. Unless you can find some proof marks, or a name, it would be hard to say much more.

Ahead of the nipple there appears to be one or two perrons although that is a strange place to find them. In keeping with tiriaq, take a look under the barrel at the breach end. Best guess is probably made in Belgium in the mid 1800's
