Service dress tunic : Lieutenant Colonel A Chisholm, 5 Light Horse Regiment, AIF

Australian Light Horse officer's khaki woollen service dress tunic. The open (step) collar has gilt brass general service Rising Sun collar badges secured by a split pin. The shoulder straps are secured at the collar end with a small 'AUSTRALIAN MILITARY FORCES' oxidised brass button, and have the rank insignia of lieutenant colonel which is a gilt pip and a gilt imperial crown with red velvet. The tunic is single breasted with four large AMF oxidised brass buttons, three made by 'A.J.PARKES BRISBANE'. The other large button, and the smaller buttons on the pockets and shoulder straps were all made by 'STOKES & SONS MELBOURNE'. The two breast pockets have a three-pointed scalloped flap, secured by a small AMF button, and have a central box pleat. The flaps also have a small press stud to hold the flap neatly in place. The larger lower patch pockets have a straight flap and expandable sides. There is a single rear vent. Leatherette colour patches of 5 Light Horse Regiment are attached to both sleeve shoulders. These are supposed to be pale blue over red but the blue appears to be dark, almost black. Brass ANZAC 'A's were definitely fitted to the colour patches, and it appears that overseas service chevrons and a wound stripe may also have been fitted, but they have all been removed. The cuffs are pointed. The tunic is fully lined with khaki cotton twill, and the sleeves are lined with white cotton twill with narrow brown lines. There is a hanging loop on the inside collar made of the same khaki lining fabric. The ribbon bar above the left breast pocket represents the award of the Distinguish Service Order, 1914-15 Star, British War Medal 1914-20, Victory Medal with MID oak leaf device, and Colonial Auxiliary Forces Officer's Decoration. There are tailored holes in the epaulettes to accommodate 'AUSTRALIA' shoulder titles, but they have not been fitted.
