Hello,
Overall, a beautiful Tschapka. Everything appears correct.
Two points, however:
---This Tschapka is the M1867 model for enlisted Ulans. (The side of the face should be 16cm). Since the crown of the frontal eagle is openwork, it is therefore an officer's eagle or possibly a privately purchased "fantasy" version.
---The Reichskokarde only appeared in 1897. However, since 1894, "Kammer" Tschapkas for enlisted men were equipped with a side post for the M91 chinstrap with domed scales. Therefore, according to regulations, this unmodified M67 Tschapka (face reduced to 14.5cm) should not have a cockade, but just the Feldzeichen (field insignia). It could therefore be an old, fanciful Tschapka, but not regulation in this configuration. In fact, it would be better to remove this cockade altogether.
