Yes Folk's,my old Mum recalled seeing zepps in her early years(approx 5y.o.)but I cant find 'em over Wexford,found them over the English midlands,but not near to Liverpool,the next possible place for a sighting in her later years.Say 5y.o to 7y.o.
This is only one of the slender threads I have,not much,but worth a try!!
Hoping,Goggy
