Michael,
The old 4th Glosters became the 66th Searchlight Regt, RA in 1938, and the old 11th Glosters became 118th L AA Regt, RA, but not until February 1942, so too late.
Are you thinking the two lads went (volunteered/posted) from the 66th to DEMS?
I'm confused because if that was the case surely they would be Gunners and not Privates, and they would be RA and not Glosters?
Any thoughts?
Ken
