Need help identifying & valueing an old parker

[Fred Beeler]

I need some help to identify an old Parker hammerless double 12 ga shotgun. 28 inch mod/full barrels. From what research I have already done I believe the gun in question is a grade 3 mfg'd in 1902. The Vulcan barrels & for-end however were made in 1909 which leads me to believe that the gun was re-barreled some time after 1909. Also the different wear patterns between the frame & barrels tend to confirm my belief. The water table shows crisp engraving & at most a 40% rating for remaining case hardening finish where-as the barrels & matching for-end show what I believe is a solid 80% remaining finish. The water table shows a Number 3 over the serial # 109878 and the letter D below the #. The barrel shows #149999 with a #2 on the bottom lug, a V in a circle , and the #4 with a small #1 just above and to the right on the right barrel flat. I will try to attach pictures for clarification. Identity & possible value would be appreciated.
