On buying tca member are required to place a reproduction orange tag on a non original train or item, if in doubt get someone from the standards committee to verify it is original, this protects the buyer and seller and future disputes.this is a professional organization and has strict by laws that all members must adhere to.
True, but I wouldn't rely on those stickers. I have seen plenty of refinished trains and reproduction parts at York that do not have them. Sure one can get someone from the standards committee, but who wants to spend the time?
Why aren't these items marked? ..... I don't know. I prefer to think that the seller doesn't know their item isn't original.
If you are interested in purchasing costly items, it is best to know what you are purchasing.
