As I see it, you’re looking at an exceptional condition A grade Gun. Ejectors are a plus, but not as big as plus as the condition. Unfortunately, nothing else about it really shines or adds value. No 32 inch barrels, no straight grip, no engraving, bottom grade of Damascus pattern, I really think condition is your only friend.
I think it would take quite a bit of luck to get anything more than 1200 for it.
The condition is very uncommon but a lot of beating the bushes finds guns like that for 600 bucks frequently enough.
