Can anyone help me identify this shotgun?

I found this musket or shotgun in my father's office. I need some help identifying it. Thanks. image.jpgimage.jpgimage.jpgimage.jpgimage.jpg

Well, it's not military. Looks to be a European trade gun, proofs may be Liege. I don't think you hit the lottery.

Typical English low end single barrel ML shotgun. Worth about 100-150.

Thanks. Any way to tell how old it is?

Put some better light on the side plate where the letters are.
It might date to the 1850's, but more likely to be a bit later. Might be dates under the stock.
