I've been corresponding with Craig offline. I agree with Raimey's dating of the gun as 1903. The rest of the markings are consistent with that date.
This is a very interesting Daly. The Daly model 80 was made and marked by Sauer is is advertised in the 1902 SD&G Daly catalog. That said, the model 80 was a pretty basic gun - flat back action, no sideslips, etc.
SD&G noted in the model 80 description that the gun was being made by the same manufacturer who made their drillings (i.e., Sauer) due to the "excessive demand" for their other models. Despite this gun being a being a non-ejector, Craig's gun is definitely a cut above the model 80. I am not sure of the model as I have not noted this gun in the period SD&G catalogs I own. While not wildly different in styling from a Lindner sourced Daly of the same period, there are notable differences. The cocking indicators on the side of the action being the item that first jumps out to me.
