If what Bill said turned out to be correct.  Whatever you do, DO NOT, "resotore" it.  In fact regardless, of whether it is true or not, restoration would only include, fitting new pegs, a bridge and possibly a tail piece.  Make sure there is a sound post installed and if there is not, make sure that one is properly installed before the bridge is put in place.  I would also suggest finding some very low tension strings for it, perhaps even gut, at least until the time that you could have it properly inspected by someone qualified to do that.  If it turned out to be a valuable antique, the very last thing you want to do is alter the original finish in any way. 

Interestingly, there are some people who collect vintage violin cases. So the case itself could have some monetary value.

Here's some information about your case.  It is apparently a G. S. B, which were the initials of the manufacturer. George S. Bond.  Turns out that's an S not a &. It was manufactured in Charlestown, New Hampshire, probably in the late 19th Century. Here's some info from an old news clipping.

"George S. Bond, a manufacturer of Charlestown, was born in that town, March 2, 1837, son of Silas and Alice (Abbot) Bond...[In 1880] he bought out the violin case manufactory that had been established in Charlestown. There was but little work done here at first, and he employed but one man. Subsequently he had to enlarge the place, and in 1893 he had forty hands in his employment and was using a fifty horsepower engine. In that year the factory was burned. Eleven weeks later his substantial new factory was ready for business. He has now a sixty horse-power engine, and he employs from twenty-five to thirty-five hands. The factory is said to be the best equipped establishment of its kind in the world, having a capacity of twenty-four dozen violin cases per day. Mr. Bond has dealings with some of the largest firms in this country..."

Great.  Keep us posted.  Look forward to seeing you Antiques Road Show.
