You will have to call Colt to find out.
Are you sure the serial number is correct? The Colt detective special was first produced in 1927 with a starting serial number of 331000,The Colt police positive special from which the Colt detective special was derived from with the serial number 153817 was made in 1918
Are you sure the detective special serial number started with AE? I do not show a DS starting with 2 letters.
The Colt detective special was derived from the Colt positive special in 1927and the starting serial number for that year was 331000 so the serial number you show of 3021 does not match up as a Colt detective special. Now if the serial number was 383021 then it was made in 1930.
Your serial number doesn't have enough numbers. The starting serial number in 1978 was S01001.
The serial number you give is too low to be a Colt detective special. Colt detective specials were produced in 1927 starting with serial number 331000.They were cut-down versions of the Colt police positive specials. Now the Colt police positive special with that serial number was made in 1912.
your colt detective special dates to the year 1949 by the serial number provided.
Please check your serial number or model number because the detective special does not show a AE prefix to the serial numbers in my records.
Colt detective specials only came out around 1927 with a starting serial #331000 and that serial number 34115 implies a date of 1910 for a police positive special.If there is a letter preceding or after the serial number then it's after 1970.
