Since it has the Bridgeport address, it's after 1935, as they were in Ohio before that sale, and move to Bridgeport. The ammo is probably from just before or after WWII, and most likely the old dark blue boxes, with yellow trim.
The complete case is nice, but the best value is going to be in the individual boxes sold. The case can also be sold too, but don't open the top of the wooden case! Open the bottom, and remove the individual boxes, then nail the bottom back on. This way, there's no chance of splintering the top, and the case will have more colectbility.
Don't expect to get super wealthy on individual boxes, but they can sell for about $5-$10 each. The cases sell for anywhere from $10-$20 each from this era; maybe more for one so complete, as they generally are missing the top.
Hope this helps.
