|Strength of tradition|
The tool has been verified by the Natural History Museum, in London, and will be entered into auction on 7 October.This is the London Museum which has the department of Ancient Egyptian snail shells, Coptic avifauna collection and the Early Islamic conchology gallery. Personally I would advise against buying unpapered artefacts like this, you never know what you might be buying no matter who says what they "think" it is. It seems to have mortar on it... This is the same auctioneer who sees a great business opportunity in selling off metal detectorists' surplus stuff. (see here too).
