Laurona 12ga value help

[mark k]

My friend asked me to help him find a value for a Laurona model 11. It's a 12ga with 28" barrels, double triggers and is choked IC/Full. The action is chromed and simply engraved. I'd rate it excellent except for the recoil pad which has cracked and collapsed. It has its proof certificate and factory envelope. It was built/proofed in 1970. What's she worth?
