Fuß-Artillerie-Regiment von Linger (Ostpreußisches) Nr.1

I recently acquired a m73 saber marked 1.A.F.I.8.H.28. can you trace the history where stationed and where it may have been dropped? I've read what has been posted and wondered for more info. Also acquired an early m73 made from a French m1822 marked 15.A.F.II.7.H.48 but that will be another story.
