Scarce Full Tube 100 Count 2mm Pin fire Ammo Percussion Caps Reloading

This is a lot of 100 count 2mm percussion igniter caps for use in reloading pinfire cartridges.  They are used internally to prime the pins inside pin fire cartridges and measure just slightly over 2mm outside dimension.  They come in a custom brass case that measures 1 ½ inches in length, unmarked likely of European origin.  A very hard to find component for Pin Fire reloading and re-priming.
