Kim- I see this is your first post- welcome!
Believe you have a Remington Model 95. These were made from about 1866 to about 1935- however- THAT barrel marking was from 1883 to 1910. Remington was sold, and the formal company name changed, so markings on gun changed.
Value? With an antique/ collectable gun, that is driven by condition- and you will need a hands-on appraisal. It looks as if the left grip may be damaged, cannot tell condition of bore, how well it functions, etc.
Have seen sale prices from $600 to $1200, but really cannot say just what yours is worth. BTW, these never had a serial number. Any numbers are BATCH production numbers (means not unique to only 1 gun)
PS- they also made a really dandy set of brass knuckles in a close encounter!
