between 1952 and 1953

1968
Sometime after 1951 .
Made in 1970
1968
If it is CLW0037116,it was after1978
The records I have show a Colt combat commander with serial number CLW0015879 as being produced in 1972.
Produced in 1967 (Production run 49651LW to 53400LW )
my guess would be late 1970's
production for commander up to serial # CLW032800 was 1978. So, your pistol may be somewhere between 1979 and 1980........................
Your light weight commander was produced in 1978.
1966
