AN Ithaca with that SN would be most likely a FLUES model. If it is without any border engraving it is probably a field grade gun. 16ga is not to be dismissed as they do have a following and bring a premium even. The value of you gun as describe would depend on the condition of the damascus barrels and the quality of the wood used in the replacement stock. Also the demensions offered by that stock. If you could post quality pictures there are members here that could better evaluate you gun. This said, in my very humble opinion, your price paid maybe makes it a project gun for you alone if you are interested in doing the work yourself. If you post those pictures you could prove me terribly wrong though!
