Miroku Corporation has been making firearms for a long time. In fact they make the rifles for Browning. After Browning left Belgium. Miroku was said to have made some real good muzzleloaders. As for placing a value on an old Sear & Robuck Hawkins.. at the time they were sold, I am sure they were not very expensive. It also depends on how motovated the seller is, or the buyer is. I would only have to guess at its value. But $150-$200 might be fair.
