The crest shown in Fairbairn’s Crests, plate 304/9 is slightly different from that displayed here. Fairbairn lists Sir Godfrey Vignoles Thomas, Bart [9th Baronet Thomas of Wenvoe (1856-1919)]; John Wellesley Thomas; George Hunter Mac-Thomas Thoms (1831-1903); and Thomas H. Thoms, of Tay-Bank, Withington, but none of these is a likely candidate for the stamp.
