[Peter Laidler]

We used to get absolutely loads of leather lens caps that were separated like yours and we'd just get a bundle together and every so often we'd send them to the 'equipment repairers' who would put a few stitches across across to sew together as a now 'one piece' set. Dunk them in the lanolin tub which they had and they'd last another many many years
