I want to sell it and want to describe it properly and accurately. I do not want to misrepresent the gun. so if anyone can tell me its a 4E, a 5E an XYZE, let me know
OK, I have a better understanding of what you want.
If I were selling it I'd describe it as:
Victor Sarasqueta, 12 gauge (2.75 inch chambers), side lock, ejectors, full coverage engraving, engraving pattern usually associated with the model 203, appears to be a light game gun, barrels ?? in length, chokes are ??, LOP ???, cast ??? and so on.
If you want to avoid misleading a prospective buy I'd suggest not identifying it as any specific model, as the guns of a specific model may vary widely in their characteristics.
