My records indicate that your 45 colt single action army was made in 1883.
You will have to call Colt with the sn to find out.
A nice pistol
about 1908
made about 1897
You need the assistance of a gunsmith.
AFAIK, Colt never made a single shot pistol
if you are taalking about a single action ??? made 1910
1873 colt single action army revolver
Blue Book of Gun Values
