An original British Army wool undershirt made by 'A.H.M LTD' and dated 1952.
This shirt is the same pattern used during the Second World War featuring a crew neck and short sleeves and could easily pass as a wartime example.
The label features the War Department arrow as well as the size which in this instance is 3. The measures at 19 1/2" pit to pit so should fit a 38" chest comfortably.
The overall condition is good and there are no real signs of wear. There are various storage marks though which can be seen in the photographs.
Overall, a good period item which could easily pass for WW2.
