I have a K line alco pair and it says both units are powered. However, I believe only 1 is powered while the other is a dummy. I saw another K line alco pair box (same part number) with the correct labeling “powered unit: dual motors” instead of “dual motors (both units)”. Historically, are misprints more valuable or it doesn’t matter?
Depends on how many typos there are, and who is willing to pay for it.
IMO, for a K-line box I would say No.
