By calling or writing to Colt Mfg. Co,. in Hrtfd,CT
Based on proofhouse.com the 1977 colt cobras shows serial numbers 60001R - 71400R & 1978 as just 63401R????????
Blue Book of Gun Values. 2nd Generation Models were produced from 1956-1978 with serial number range of 0001SA-73000SA 3rd Generation Models were began in1978 with serial number range of 80,000SA-99,999SA IN 1978. at this point the "SA" suffix changed to a prefix beginning with SA01001- SA99,999 during 1993, and began over, this time separating the letters "SA, and starting with S02001A.
Your serial number doesn't have enough numbers. The starting serial number in 1978 was S01001.
The list I have only goes to up to 1978 ending with 99999SA. After 1978 the serial numbers started with SA01001.So a few years after 1978.
http://proofhouse.com/colt shows 1930 for the serial number but without the "S" My production date list shows 1930: 383001-400000 and 1978 starting S01001,so it would be 1978 or after.
You will have to call Colt. Published serial numbers stop at 1978
January 17, 1978.
Subtract the first 2 numbers from 100 = 1978.
Sorry- no known public SN database on these guns, and the firm went bankrupt and closed about 27 years ago.
The Colt police positive special serial numbers I have end in 1978 with 59999R so I would have to say a couple of years after that.
