Like a lot of people in this country at the moment I am waiting for delivery of several items I ordered online, hopefully in time for Christmas (hope is fading). One of them is a reading lamp from a firm founded and owned by one Alex. Pratt OBE. He says on Wiki that he is from a Services background in a mining family, doesn't say whereabouts in the UK.
As for Vilent/Vilant, the surname was common in St. Andrews and Kingsbarns, acc. to Scotlandspeople. Our local historian George Gourlay, in his chapter about the seizure of the Danish fleet in 1807 in "Our Old Neighbours", mentions drill-master Vilant drilling the Volunteers in the fish yard in Anstruther in that year. They were naval reservists, and were called up for that controversial pre-emptive strike to stop the Danish fleet falling into the hands of Napoleon.
