Wooden carrying case for both H4 and K1, probably made in 1938 for transporting them both to the Empire Exhibition being held in Glasgow that year, but possibly also with adaptations in the 1960s. The box is lined with padded baize and has separate compartments for the two watches, H4 on the left and K1 on the right, both fitted into separate mahogany deck-boxes lined with green baize, these boxes almost certainly adapted from Hamilton Model 22 boxes (1942).
