Dennis - Most error's or Proto types that surface have a history or trail behind them and can be verified. If it is a Proto type one would seem to think it would have surfaced sometime ago like the other proto types that are known. If it was an Error one would think there would be others (I have never heard of only one error of a certain strike) but none have surfaced so it does raise a few red flags in my oppion which doesn't really mean a thing.
