Very nice! I've got an H&R licensed hammerless version made about 10 years later. (Can't get the pic file size small enough to post.)
Yes, besides the "hammerless" feature, you will notice a conspicuous pin through the center of the slide, and grip safety. All changes were incorporated into the H & R SELF-LOADING CALIBER 32. The Worcester, MA plant produced a total of 34,500 units from 1916-1924.
