I am in no way an expert on P shaped hilts but I do read many maybe going by a basic profile and thinking it must be a 1796 hilt.
The top sword looks like a late Prussian artillery sword and the second by Simon also late and maybe infantry and of the continent.

Just a few there and I'm sure more on Old Swords for browsing
