As background , C M Budd was a maker of gun accessories and made an outfitted demonstration case of his company’s items beside a Parker backaction lifter. Photo 1.

In that case is a small vial of pins. They are of varying lengths and are thin at the extended tips. They are not Parker plunger strikers. They do not look like any Parker parts. Photos 2 and 3.
Any ideas what they are?
