I a trying to figure out which Royal Artillery (T.A.) unit Major-General Edward Frederick Lawson Burnham (4th Baron Burnham) was Honory Colonel of between 1948 and 1953. The London Gazette only notes that he was Honorary Colonel of a R.A. (T.A.) Unit, but not which, and there is no metioning of this in his obituary or entry in Who Was Who.

Any ideas?
