When first introduced, the 1937 Pattern binoculars case could only be worn on the belt as part of the full set of accoutrements. In reality there were many instances where an officer might want to carry the binoculars on their own, slung in their case over his shoulder. The military quickly recognised this shortcoming and developed a webbing cradle to place the binoculars case into and which allowed a shoulder brace to be strapped to it as a shoulder strap. This was a complicated solution to the problem, and a much simpler way of resolving the problem was to attach a pair of buckles to the sides of the case. For those cases already manufactured, this was achieved by the simple expedient of riveting a pair of buckles to the case:
The buckles were sewn to small pieces of webbing and attached to both sides with a pair of pop rivets:
Apart from this modification, the binoculars case remains the same as all early production, so has C hooks on the back to allow it to be worn on the belt and the compass pouch to be attached above it:
The box lid is secured with a single press stud on the front of the case:
A thick piece of felt is fitted to the base of the case to protect the lenses of the binoculars when they are placed inside:
The other side of the rivets used to hold the extra buckles can be seen inside the case. This case dates to 1939 as can be seen by the stamping on the underside of the lid:
Whilst riveting the buckles on was a good expedient to modify existing cases, new production examples could have the buckles sewn on from new and this can be seen here with a Second Pattern case alongside a modified first pattern:
With both the modified first pattern and second pattern example, it is just an unmodified first pattern case I need to complete the evolution of this piece of webbing and have the full set.
