Fluffernutter,
The gun pictured is a low cost, working mans box lock. Such guns typically sell on the on-line auction sites for roughly $400.
If the gun was made by Victor Sarasqueta (and the jury is still out, waiting pictures of the barrel flats and water table), my best guess is it would be a model 98, made circa 1940 1950.
Here are examples of the photos we need to see to determine maker and when it was made:
Barrel flats of a Victor Sarasqueta 16 gauge. Note the running rabbit (preceded and followed by the letters V and S) trademark of Victor Sarasqueta, and the proof year code of E*1 (1959):
Water table of the same gun. Note again the running rabbit trademark, and Victor Sarasqueta makers mark of AM:
Hope this helps.
