1917 DWM Artillery
 

I was interested in this artillery, but it lacks the bore diameter as far as I can see and both of my artilleries have it under the barrel. Does this mean this barrel has been refinished or somehow left off? Thanks, Curt http://www.gunbroker.com/Auction/Vie...Item=531207006

Tough call. There are halos on the barrel number and the toggle pin is white. But the grip frame numbers show no halo and looks just a bit better than the rest.
As to your question on the bore diameter, I'll not go there but hope someone more knowledgeable in such matters chimes in in just minutes before the auction ends.
Overall I'd say that the gun looks very nice and would not hesitate to bid. But then I just can't honestly answer your question on bore diameter. I guess I'd draw a line in the sand that covers some rebluing (but correctly done and without buffing) and see where the bidding goes.
Good luck and keep us posted.
