Hi Mike, another nightowl eh, I do hope your water incident was not of the personal variety ! ;-)
Thanks for reminding me of the witnesses, especially Arthur Eagles born abt 1879. I now see he was clearly a different Arthur than the WW1 soldier I mention above, and Arthur is not the rarest name, but maybe a family link ?. ?

I do hope the sample results arrive soon and are in line with your expectations and no lasting harm done.
