Whoops!!! that could have been me, had the forum been around in the mid 1950's. I stayed with a school friend near Llanfairfechan, on the Menai Straights, during one hot summer. Exploring in the hills above we found a load of metal debris and fins, mostly damaged, however a more perfect set of fins was partially sticking out of the close cropped turf between the clumbs of heather. Out with sheath knife, most boys had them in those days and not for protection, a quick cut around the turf and soon we had the fin free but behold
there on the end was, more a cylinder, squarish in profile and about 2 in diam. Just then we found another more promising fin, slightly larger, and repeating the process and more of a struggle, two pairs of hands and an enormous heave!!! We tumbled backwards and lying flat out, saw a huge, nastily tapered looking bomb thing on the end of this set of fins. The nose cone was leaking acid like substance, that sizzled ominously. The whole appearance was a portant of evil so, we backed off and on arriving back at my friends home we reported our find.
I was due to travel home the next day, but when I met my friend in the following term, I learnt the bomb disposal had come out after the police had inspected out finds. The first discovery was a 2in smoke mortar round, the latter a 3in HE mortar round. when they were exploded the bang was heard in Anglesea.
I think that was the first of my 9 lives
