between 1952 and 1953
Production date was 1968.
1968
Sometime after 1951 .
1968
If it is CLW0037116,it was after1978
Made in 1970
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.
The Colt commander with that serial number was made in 1955.
