Shotgun ID help

[Wraith_3]

I think this might be a British Parker, Fields & Sons 11 gauge shotgun. My dad had this in his CW collection so I assume it was possibly used in the CW. I don't know anything about it, but was trying to research it before I list it. I just don't know much about it other than some British small arms were used by both sides.
