IRA photo of F Coy, identified as "G R Thompson, SS" (presumably Secret Service) and that he was an Intelligence officer
I am unclear if there are 1 or 2 men with the ADRIC numbers 593 and 603. The entry in the Alphabetic register indicates that they are the same man, but their details are quite different. The entry for 593 has him as "G Tomson" and a Sub Lt in RNVR - he joins 17 Sep 1920 and resigns 7 Jan 1921. The entry for 603 is for " Lt G R Thomson" joining on on 20 Sep and serving until demobilisation on 21 Jan 1922. They are two different men
