[quote=“VinceGreen”]There was no British involvement at Verdun, way too far south. Would this be for equipment we supplied to the French? Or US at Argonne I suppose?
Tony, is there a safety concern with those Buckinghams or the Brock?[/quote]
I don’t think so.
The Brock is only sensitive to striking and does not contain free nitro glycerine.
The Buckingham contains yellow phosphorous sealed within the envelope by a fusible metal plug, and that is within the case mouth.
I have never heard of a problem with either, and certainly mine have been lyiing quite peacefully in the cabinet for many years. On the other hand, I know of at least one case where a German B-Patrone has exploded spontaneously in a cartridge collectors cabinet, and these are normally treated as quite safe.
