I would probably not say that they were improperly done but that the gun was recase colored not using the bone and charcoal method. The majority of the viewers on this forum are of the opinion that case coloring using a "torch" or cyanide method is not what we prefer but that is not to say that any other method is "improper". We must keep in mind that beauty is in the eye of the beholder. I have purchased guns from individuals that had been "torched" and they thought that they were beautiful.
