I would have to guess around 1978/79 My book only goes up to 1977.......
You will need to call Colt to find out.
Do you have a digit missing? The list I have shows gold cup national match .45 starting with 70N01001 in 1970
The model 1911/1911A1 Governmental pistol with that serial number was produced in 1944.
It would tell the year when it was produced.
it merely refers to that number produced for that year, and a number to be used for arms inventory...........................
There is no way to answer since you did not provide a serial number. You can call Colt and they will tell you. The Blue Book of Gun Values has sn data as does the Colt website.
Produced in 1934.
The 69C prefix to your serial number indicates that it was produced in the year 1969.
Need a detailed description of all markings
A Colt police positive special .38 with sn 262352 was produced around 1922.
