Research Assistance - Inherited Parker Brother Shotgun

[Benjamin Elliott]

Hello all, I recently inherited a Parker Brother shotgun from my Grandpa and I am now doing some research on the model. This site has been very helpful in explaining to me how to verify the manufacturing date and what the various meanings of the stamps on the gun. What I've found so far, and please correct me if I'm wrong, it was manufactured in 1899 with Vulcan steel, it's frame size is "2", it's barrel weight is "4-1", and its rating grade is "V". I've never owned or done any research on Parker Brothers shotgun, besides this site, If someone can shed a little more light on what exactly these marking mean I would greatly appreciate it. I also can't seem to find the meaning of the gold shield on the buttstock. Again, any assistance is appreciated, I've also attached pictures to reference. Thanks again.
