Dear Darcy,

Thank you for contacting Mearto with your appraisal inquiry. The apprised object appears to be a Remington Rolling Block rifle made ca. in the 1890s. It has a blued octagonal barrel marked "E. REMINGTON & SONS, ILION, N.Y. with the serial number 11651. The decor is a later individual addition.
This piece is in medium condition and there are no serious damages visible.
An estimation would be between 300 to 600 USD.
This estimation is based on actual recent past recorded auction sales of comparables. Retail "asking prices" can be higher and vary.

With best regards,
Georg
