Very hard to do with out the gun in your hands.
When you get the gun PM me and give me your phone # and we can talk.
Ithaca made allot of different grades of side by side they also imported SKB shot guns.So to tell you what you have I would need it in my hands.
But with the gun in your hands you can answer my questions and we can figure out witch one you have and what grade it is.
They made changes all the time so each side by side have different things on them witch puts them into different grades.
