To all,
I received this email from a German friend:
"Dear John, you never are imposing! The pictures with red background is a Prussian friction primer (Reibzündschraube, ~1845 to 1900), the initials will shown Feuerwerks-Labor, may be Spandau or Siegburg. That's original! The primer with coin ... I never seen it.
Glad to hear from you and
Kind Regards
Peter"
