I'm shooting from the hip here but I believe that "had made" is "past perfect" tense as opposed to just plain old "past tense". The idea is that the action was completed at a point in time and is over and done with (grammatically incorrect, I know but, well...). Past tense means that what was made in the past might still be being made now. The Aorist tense in Greek is akin to that, signifying an action being started at some point in the past and continuing on into the present. Perfection means completion.
