You will have to call Colt with the sn to find out.

AFAIK, Colt never made a single shot pistol
10 years it is not 10 years but i do not Know how old it is
50-250
value depends on condition
A Colt single action 1860 army with that serial number was made in 1866.
your colt single action was made in 1970.
Your colt single action army dates to 1881 with the serial number you provided.
My records indicate that your 45 colt single action army was made in 1883.
If it is Colt single action army, then it was made in 1889.
I assume your single action is pre-war ? If so, then made about 1907. As to the caliber, check markings on barrel. that should give the caliber.......
