I cannot advise you about the value of the gun but do not compare this gun to any E.J. Churchhill. These guns were imported by the Ellett brothers until 1993. Most of these guns are in the $200 to $500 area with out much demand.
Evaluate the gun on your own keeping in mind that very little parts support is available if something breaks.
1993?, I bought a Churchill in 2000-2001 and I think the box had Ellet bro's on it.
Mine was 20ga Windor sporting, This gun had better wood,fit/finish than any of the 3 Beretta 686's I own. It was a Franchi Veloce with a differnt name.The ONLY reason I sold it was ,it didn't fit at all, and had the worst scores of my life trying to shoot skeet and sporting clays. I bought it for 900$ sold it 20-25K rounds later for 400$.
I wont own another.
