Is it possible to date these two rifles? This has to be one of the earliest examples of a Monte Carlo on a rifle. As the name suggests, they were originally fitted to trap guns.

The cheekpiece of the lower rifle is identical to the one on my 1916 Newton Rifle (a factory option), but one I had not seen on a custom rifle other than one built by Robert Milhoan shown in Phillip Sharpe's book, The Rifle in America.
