Recently I found a General Service button marked same as yours, D. Evans Attleboro. Mass. If I remember D. Evans produced buttons from 1845 I think until 1945. Not positive on the 1845, infro. I had for a metal detecting club I've since discarded. Hard to find much on D. Evans, but it's out there. What does the front show?
Icewing, some friendly advice... that website is notoriously inaccurate in the dates it gives for various backmarks. The mis-information there can seriously mislead people who need the correct information. That website even repeatedly miss-spells the name of the Waterbury Button Company as "Waturbury." No offense, but I don't think that website should be recommended to anybody.
A much better ONLINE backmark info source is the Ridgeway Civil War Research Center. It has an extensive section on buttons AND their backmarks. Go to the following URL and click on "Click Details" under each photo. Catalog of button backmarks
Creskol, I do not recall ever seeing that particular D. Evans backmark, with a "circle of arrowheads" (or hearts?) on dug civil war era buttons. But of course my experience should not be considered proof that it's a post-civil-war backmark. But the Ridgeway Research site says it is post-civil-war. Scroll down through the photos to see your Evans backmark and info. Button backmarks, D Evans, Attleboro Massachusetts.
Of course, no info-source shows EVERY variation... so along with the Ridgeway website's section on button backmarks, I recommend buying the best book on button backmark time-dating, the inexpensive ($29) "American Military Button Makers And Dealers; Their Backmarks & Dates" by William F. McGuinn and Bruce S. Bazelon. The backmarks-book by Warren Tice is also excellent, but it's out-of-print and therefore is very expensive.
I went back to look at the D. Evans I have. I was part wrong, it is not a General Svc. button, I at first thought it was Navy, but instead it is a early Marine Corp button. Back mark reads, D. Evans Button Co. No. Attleboro Mass. This one has no heart/arrow design on it. It is dark with black paint on back, and given where it was found, I suspect WWI era. Date time line for Attleboro, Mass & No.(North) Attleboro, Mass. I currently do not know. CannonballGuy seems to know his stuff though, I to will check out his recommendations.
On your behalf, I checked the list of D. Evans backmarks in the McGuinn-&-Bazelon book on button backmark-dating. It lists only two Evans backmarks with "North" or the abbreviation "No." and says both are from after the civil war era. One which is the same as yours, except for the word "Button" is on a post-civil-war US Navy button.
