Yes- the stiches are white. Perhaps it is the black calor- it is an "unusual" black but you have a really nice holster.It should have WaA 841.
Holsters in still good conditions are not so rare- one is dated 1915 the other undated but late (I think 1918) but yours is like new and that makes the difference!
