I now have his service record and although struggling with some of it am managing to make sense of it , the last entries seem to be a jumble of units Down graded from AT to B6 TOS H&SC from 52 RHLL P/A to 2ca pool from 41 RHA pool. Remain on X(1) list Med examination found fit for further service.Med Cat 6 Posted to X(vnta)list for class A he was then posted back to UK for discharge . Notification of Release form states . Unit Regiment or Corps:- RA Field, Last serving with 307 P Mil Goo . (or Gov) Det. Any help in identifying any of the above units above would be much appreciated.
