i just got back from my trip, so i'll post a photo of the back later this evening. nicely made with the silver, enamel, gilding, and multiple piece construction.
thanks for the tip about the flyball governor DCMatt, that's definitely it. those seem to have been mostly used with steam power...so maybe something pertaining to trains, which i think were pretty important for 19th C. militaries. (not 100% sure it is military, but as you point out it has a fasces motif, so i think that makes sense).
