I was lucky to see Barrys engine a couple of times and watched it run sometime in the 1980s. At an much earlier exhibition i viewed his embryo merlin, just a large chunk of alloy with pockets milled out. What a craftsman. He was always a very private man but still active in 2008 as he exhibited his Eagle 22 in the ME exhibition and came away with a cup. A picture of him is in issue 4338. The last time I heard of him was in about 2018 when a someone mentioned the they had spoken to him, but I really can’t confirm that.
