Don,...he is wearing what appears to be fraternal medals as well, but as my area of interest is frontier military marksmanship I am not that interested in the other medals.
Forgive my ignorance but, is this device meant to adjust the rearsight of a rifle in height for a given distance (even "roughly")?Here is a Stadia which was one of the earliest awards, they were brass and silver, which is rare.

It's used for estimating range independent of the rifle sight and type rifle. The cord is used to hold it a fixed distance from the eye, view a man height target through the slot, align the top of the slot with the top of the target and move the slide until it hits the bottom of the target. Then read the range off the scale to the side of the slot.
45govt's is a bit fancier than the one in the below drawing but the principal is the pretty much the same. Looks like his might have you bottom the target in the slot and move the slide to the top of the target.
Its a great accessory for long range shooting with a black powder rifle since the low velocity/high trajectory make range estimation critical.
