More info I've found, although useless, it is somewhat amazing what can be found so quickly on the internet.
This gun was ordered by W.G. Dunn of Madison, Wi. I found a directory listing from 1917 which listed W.G. Dunn as living as 321 North Brearly St. Madison, Wi. A quick search of the internet turned up a picture of what is likely the first home of my gun. I wonder how long she lived there with Mr. Dunn? Looks like a nice neighborhood.
