Pam, TD is Territorial Decoration, which ties in with Territorial service in the RAMC. The following is from www.northeastmedals.co.uk The Territorial Decoration (1908-1930) Instituted 1908 in the wake of the Territorial and Reserve Forces Act 1907, which saw the formation of the Territorial Force from the reorganisation of the old Volunteer and Militia structure of the British Army. This decoration therefore replaced the Volunteer Officers' Decoration which had been in use from 1892. The Territorial Decoration was awarded for 20 years commissioned service, although service in the ranks could be counted at half the rate and war service at double the rate. Description: a silver skeletal badge in the form of oval oak wreath "tied with gold" 45 mm high by 36 mm wide, containing the gilt finished crowned cypher of King Edward VII or George V as appropriate. The reverse is plain except in the case of the earlier issues which are hallmarked. Suspension is by means of a free ring. Naming: issued unnamed although frequently encountered unofficially engraved in various styles. Ribbon; 38mm wide dark green with a central yellow stripe. Regards, Rosie Ansell
