Metal box approx. 11 x 8 x 2.5cms. Printed to the lid "Horlicks Tablets - A Complete Food - Public Emergency 24 Hour Ration - As Supplied To The Air Ministry". Interesting to note that there are at least 2 slightly different versions of this size of tin each with slightly differing text. This is also unusal in having a painted 'body' as well as the lid. Light wear but in excellent overall condition. Empty. Stock code M16770.
