The plot thickens…

If the archaeologists were doing a site investigation, then I suspect that they were not digging that deep (though I know nothing of the local geography/geology). Bet they moved a bit sharpish when they realised what they were scraping with the trowel! 😮

If there were two bombs close together and close to the surface, I wonder whether they were simply “mislaid” and got covered in rubbish at some point afterwards, perhaps buried by later landscaping? Of course as Colin says they may have been hang-ups that finally fell off, so the two may be together by chance. Just wish they’d say a bit more about them!

I wouldn’t worry too much, I have worked with some of those archaeologists probably before and they don’t do things too swiftly. It took a week to uncover a grave containing a horse and a soldier after i had found it for them at Lakenheath.
