I recently acquired a bag for the British small box respirator (SBR). However, it is missing the small brass stud from the strap (the one that buttons into the leather tab) and the spring spacer to keep the filter base off the bag.

Does anyone have a spare of these I could buy? I would imagine the studs must turn up regularly in France, and the spring from a US bag would do.
