Yes, I was going to mention this as well. The trick (which is not hard at all) is to make the marking declaring it a replica hidden from normal view, but in such a place where it would be discovered easily during an audit or inspection. And, yes, DEC panels did have minor variations in artwork. For example stock green PDP-12 panels come in at least two versions - early ones have lower case in the markings, but later ones do not. -- Will
