Deconstructed Brake Cylinder

The parts of brake cylinder from Barclay diesel No.7 having been taken off the locomotive. The perished diaphragm is in the front centre and to the left is a "new" leather one that was found in the stores probably dating from the 1960s or 70s. We are going to try and source new modern ones as the leather was very hard and inflexible.
