Need identification before restoration

[Jim Copenhaver]

My wife's father just recently handed down a Parker Bros. shotgun which is a family heirloom. I've taken it to a gunsmith who recommended I converse with this group before he started restoration as it seemed a bit unusual.

This is the information we were able to gather from an initial look along with pictures.

Serial Number: 166 F (best guess - see pictures)
British Proofed
30 inch barrel
Lifter Style
Extra Engraving
Locking Lug
Black Powder
12 Gauge
Laminated Steel Barrel
Barrel Text (best as I can make out) "Parker Bros. Maker Meriden Conn Laminated Steel.
It has some proofs engraving in the barrel as well

Thanks in advance for any assistance in identifying this model!

Jim
