What is the age and value of an 1885 Winder musket serial number 131255?

The serial number lists do not include details between 1913 and 1923, but the final number assigned in 1923 was 139700, so it is a pretty safe bet that yours was made in 1922 or 23. My guide suggests a value of $1200 in NRA Good condition or $2000 in Very Good.
