Always liked the 1907s. Especially the gangster era extended magazine models offered to police departments.
If there were better (any) ammo availability I wouldn't mind owning one. Even before the Ammo Panic of 2020, you had to either reload or search vintage ammo merchants.
Thanks for sharing yours.
(I would say that the 1907 was the grandfather of the M1 Carbine, but not of Assault Rifles as I don't think it was ever offered with full auto capability. That title goes, imo, to the aforementioned STG-44)
