As compared to ACW, as you might suspect we rely more on replicas. Not surprising, as the availability of originals are practically non-existent in this day and age.

This was always my philosophy as well. I don't think you have to be 100% decked to the nines to be convincing.

That wasn't something that ever bothered me that much.
