Montana, The gun has a bit of an interesting history.It has one set of nitro proof marks that would normally put it in the 1896-1904 era however the Macnaughton records have it listed as a best ejector with damascus barrels delivered in 1923.The concensus is that the action and barrels were proofed in the white during the earlier period and the gun was finished and delivered some 20 years later.The barrels are 29" x 2 1/2" x .023 x .023 and measure as built and proofed. I had to pry it out of the fingers of a good friend of mine in England about 5 years ago.I found another composite pic I had on file and will attach below.
