It is nothing at all to do with which part of his anatomy is missing, but the fact that the same part is missing from two identical trays. That would suggest that they were probably not hand-painted/coloured. No one person is likely to have made the same mistake twice, and unlikely that two people would make the same mistake.
If you hang around then you'll understand that the people on this forum are from all over, and do enjoy helping people when they can ... and also enjoy having a laugh once in a while. No offense was intended to anyone. I am guilty of poking fun at a tray posted on ebay, not your tray, as you haven't posted a pic of yours. If yours is different, then I'm sure that we'd all love to see it.
