The holster is an M-1916 type and was made in 1918 by the Clinton Saddlery Co., Clinton, Iowa.
The F.W.T. stamp is the on-site govenment inspector who passed it.
The belt is a Vietnam era M-1956 cotton belt.
They were standard until 1967 when a new nylon belt design with a Quick-Release "Davis" buckle came along in the M-1967 belt.
THe holster is in remarkable condition for being 90 years old!
I imagine it would have a value of around $100 or more to folks who collect stuff like that.
