Well, I am thinking we have some different ideas about craftsman ship, the definition of craftsmanship.
It does not not make anyone a bad person--but let's try and get on the same page.
I think of craftmanship as the ability to get parts too fit correctly.
The parts made today are better and come to the manufacturer with better tolerances. This allows fitting with minimal work to adjust to fit.
Now if you buy a part from a supplier to upgrade a, say a Colt, to better suit your wants and desires then most likely there will be the need to do some work on the part.
I think that is also true on most of the parts supplied too a manufacturer, even today, but if it is his part supplied to his design specs, there is less of this fitting needed.
Sure, there are EXAMPLES of products put out which are NOT the manufacturers desire of quality. There are even manufacturers who are woefully lacking in quality inspection. These are not what I am thinking of though.
Colt has, depending on who owned it and the period of time being discussed, put out some cheap looking stuff--maybe even cheap stuff-- this is not what I see, in the original post, as the question.
I see the question as being about putting out a decent--not gunsmith quality or personal build quality--well functioning weapon with good quality parts that are well made and fit.
Weapon may not be--and probably isn't--dehorned and polished. Then again it never has been.
