A lovely vintage saddle case.
These are versatile little cases which can carry items such as sweets, keys, pocket knives, twine, small radios or chocolates.
They are designed to be attached to the offside d-rings on the saddle behind the rider and as well through the girth strap. But they can also be used offisde or near-side in front of the saddle attached to the front d-ring and breastplate straps.
This little case measures 5 1/2" across the face, 3 1/4" in height and 1" in depth.
This one isn't quite long enough for an iphone but will carry most other small items to free up pockets.
