#V814XX was made in 1979.
The V series started that year, beginning at V01001 and went to V88373 by the end of the year.
You'll get a lot of discussion on any gun about "good" years and "bad" years.
The truth is, guns are not vintages of wine.
There are NO "good or bad" years.
There are "good" and "bad" GUNS.
Attempting to buy a gun based on year made will either cause you to buy a dog made in a "good" year, or pass a gem made in a "bad" year.
In general, all gun brands, including the Python, saw quality fall since the 1960's.
To get a good quality Python, you have to LOOK at individual Pythons and select one that looks good.
I've seen Pythons made in the 1950's when quality was supposed to be great, that never should have left the factory.
I've seen Pythons made in the late 1990's when quality was supposed to STINK that were some of the finest Pythons ever made.
Again, you have to judge a gun on it's OWN merits, and pretty well ignore the "year or era made" business.
