Thanks gentlemen. The goal is not to carry it, but to have a functioning holster for display. I have holsters for most of my collection. Japanese Nambu’s have high value. This one does not.
I would prefer to have a replacement flap made which I could see into the holster itself.
The flap itself has deteriorated much more than the holster itself. That surprises me.
Can it be fixed? Probably not. Being a novice in the leather world, where would I start to obtain a new “flap” piece, cut to match, and color match? I’ll keep the original flap separately.
