Looks to have that type 89 scope rail to nowhere as well.
Good catch Bubbaz, I missed that in photo #2. That combined with the 16” barrel, Bayo delete, and spring clip on the cleaning rod hole means this gun is a Navy Arms Cowboy Companion.
As an aside, the commonly mentioned ‘rail to nowhere’ is a totally different animal found on K-Sports guns. Type 89 rails fit many various type 89 scope mounts. Yes they are hard to impossible to find, but they do exist. No off the shelf mounts exist for the KSI rail to nowhere.
