To determine the age of a 32 caliber Secret Service Special revolver with serial number 178866, you would need to consult production records specific to that firearm model and manufacturer. The Secret Service Special revolver was produced primarily in the early to mid-20th century, so the serial number can help establish a rough manufacture date. Generally, collectors and firearms experts can provide more precise dating based on the serial number and other features of the revolver.
Don't know value, but a police positive special with that serial number was made in 1946
