While this is indeed a nice set, I think this guy is a little high in his BIN price. What do you guys think? Link here.
Its an interesting auction that I have been watching. I'd say its truly a unique item as a display item. I am not sure you would want to break up the display and use the items as individually 6 injectors, even NOS ones would not total the BIN price.
I'd tend to agree with you that the BIN price is probably a little overoptimistic mainly because injectors don't seem to be pursued by collectors in the same way that Gillette DEs are. That said, as a display piece in such condition, you are really probably looking at only a few left in existence.
