FENIAN RAID 1866 (Captain J.A. Carlow, G.T.A.). Naming is officially impressed, the "o" should be and "a" in his surname. Contact marks, edge nicks, better than very fine.
Footnote: Captain John A Carlaw is shown on the roll of the 294 man Grand Trunk Railway Brigade and is listed on page 183 of the "Canada General Service Medal Roll, 1866-70" by John Thyen.
