The original poster asked for a value assessment and that's what he got. William Larkin Moore sold a gun identical to mine at listed $5000, an unengraved gun fitted like a Purdey. It was probably a mid sixties gun like mine, I'm sorry I didn't buy it. The OP's gun is a bit rough and I think the $1500 value mentioned is a fair price, but only if it is a smallbore. My gun and the Larkin Moore gun were underpriced at $5000. The Moore gun sold rather quickly as I recall. Each gun is an individual and early guns can be as well built as the recent guns. I'm glad my gun didn't get the engraving that the OP's gun got. The dogs have no features and most of the engraving was done with a punch, overall very amateurish. Mine and the Moore gun were elegant beyond most any other Spanish gun and are absolutely plain and unengraved, with wonderful case colors.
