Welcome to the Forum. You have a 32 Safety Hammerless, 1st Model, shipped around 1897.
I am sorry to report that the gun has seen some harsh buffing and a re-nickel job, so the value as a collector piece is gone. The factory made a quarter-million of these guns and value is generally low. Your revolver would be worth $150 without the ivory stocks.
Ivory has become a hot topic of debate on what is legal and illegal to own, so prices have dropped as fewer and fewer collectors want to deal with the issues and laws. The maximum amount of ivory that is legal today is 200 grams or about 8 ounces. I think you might get $150 for the stocks alone, and probably not much more if you sold the gun with ivories. I do not believe that the stocks will show as original to the gun since there is no gold medallion inset into the top round. Pearl or ivory stocks made after 1893 all had gold medallions. Often big distributors would buy basic guns and add fancy stocks to help with sales.
