That's a pretty late gun in the Baltimore Arms line. I have one very similar in the 1700 range. Engraving and stock decoration are very similar. You are lucky to find your gun. My impression of Baltimore Arms higher grades is that metal fit was quite good, the engraving somewhat unusual and naive, and the stock checkering and carving maybe the best of all the doubles of that time. If you want to see pictures of another D, you might find an article on the Company by Dave Noreen, as I recall. I gave him photos of mine that are published there in the Double Gun Journal. If you'd like some pics of that one and others, email me. My address in in my Profile.
