as I unbderstand the Dreyse philosophy the safety must not simply block the firing pin but uncock the firing pin string similar to a Carcano action. is this the case with this rifle too? see it on every Dreyse gun I had in my hands before startet with the early needle fire rifles.
did you believe this rifle startet as a 6mm Flobert? the 22 short, long and long rifle were not so much in use in this times.
