Above:
"Cut that tape open, toss the box, plug her in and enjoy."
Not the point.
I do not collect PW items (I do casually "collect", when convenient and a value, other things - like Williams/Weaver brass locos), but, when I see a PW (for example) item that is also in the original box, I do understand the additional appeal of this. I won't buy it, but I get it. If the box is already gone, fine; but if it's there - yes, it adds intellectual value to the piece and, I guess, monetary value too.
