That is a find of high historic relevance imho.
As far as my knowledge goes 24 L.W.R. translates to 24th Landwehrregiment. Landwehr was the reserve or second-line formation of Prussia. Therefore the musket (an M/1809, last flint musket of Prussia btw) was an older hand-me-down form the active units.
It is highly likley that it was fired in the Napoleonic wars, was carried on a weary but prooud shoulder through Paris and maybe was even there on as the Prussian went into the Battle of Waterloo.
Believing that this belongs to an firearm that was in two conflicts that changed the world (Napoleonic and Civil war), I vote Banner!
