Do you have a photo that is straight on to the image?... so hopefully any characteristic details may be seen better....
The image appears to be a photographic copy of another original image.... These were common in the 1880-1920 era... to produce a copy of and/or enlargement of an older image... These are usually found on heavy card stock... Since it is a photo of a photo, unfortunately the small details tend to get washed out and fuzzy... Also common to find them retraced over and tinted to bring back some detail in the blurry fuzzy areas.... The tongue & wreath style buckles were popular with military, militia, fraternal groups and some civilians for a number of years both pre and post war...
