Swiss M1914 Sawback Pioneer's Bayonet, 1938+ production with postwar frog

Description

This is an unissued Swiss M1914 Sawbacked bayonet, marked Elsener Schwyz on the ricasso. The frog is marked J. Justrich Sattlerei Walzenhausen 80, dating the frog's production to 1980!  The scabbard includes a P marking at the throat. Issue marks including serial numbers are not present, meaning this bayonet was likely never issued formally.
Locking button works correctly with no issues
The hilt, crossguard, and scabbard have spots of corrosion, I have not made an attempt to clean them off as restoration and conservation isn't my speciality. Pictures are included in the listing of said corrosion
