Never heard of a Rohm with this maker mark.
I don't buy it, but I'm not close minded either. Show me a Full Rohm Boker or even a partial with this maker mark and maybe we can consider it. Till then this will not be accepted.
As far as Bill selling his as a ground Rohm, well nobody is perfect, we all make mistakes and Bill is a straight up guy. I don't believe he ever knowingly would mislead anyone. I just happen to think on this rare occasion he's wrong.
