The 28" barrels are definitely uncut. They are also damascus, which makes me wonder if your original tubes are as well but were "re-blacked" somewhere down the road.
I had wondered that as well, although they are marked "W.R. C.M Steel". The barrel maker's initials look to be J.T.
I used the Westley Richards website
http://www.westleyrichards.co.uk/GUNS/Gun-Histories_2/History-Authentication to date the gun, it's 146xx. The 16 gauge barrels are 161xx, which date to 1900 - and are marked "Special Steel".
The trigger guard does indeed have a fine depiction of a long haired retriever? I'll try to get you a picture.
Currently I live in a no man's land for reputable vintage gun shops - the North West corner of Arkansas. If anyone knows a good gunsmith in the area, please let me know. I have no intentions of firing anything until the gun is thoroughly checked over.
