G2DC 1961 England

Jack Metheun Leslie Drudge-Coates was born in 1902 (Isle of Wight, England). He died in 1973 (England). In 1969 he was a member of the Board of Directors of the Yasme Foundation. His operations as y-DCR and ai-2KX were both in India.
Also, The "Brindiv Signals" on his other cards is the abbreviation of "British Indian Division Signals."

And a side note that has nothing to do with Ham Radio. His 15-month-old daughter died 11 Feb. 1943 and is buried in Mhow, Bengal, India. I found a photo of her headstone on the internet. This does not match with the dates of his Indian operations, but the father's name was J. Drudge-Coates of the Royal Signals.
