No Us markings. I figured it was a model 1902 officer's sword, as Diggumup pointed out.
But it might be an academy sword. I've haven't had time to research it.
Research the violin well before you sell it. Especially the bows, they can be pricier than the violin itself. An old girlfriend of mine picked up a violin at a sale and the violin was pretty worthless, but she sold the bow for $800. Those old lodge pins might be worth more than you think also. Great buys all around!
