They look like nice original pieces to me Luke!!
Always possible it has been reblued, more pictures can clear that up.
Lets talk about low values, then you can go from there, checking e-bay can give you guesses, but lets say, if all stitching is intact on the holster, they go from $85-$150, loading tool, depending on how thye are marked $45-$85 (and up), pistol, at least $500, (shooters go for that), probably closer to $750, depending on what Frank said, Condition, condition, etc.
Oh and I like Erfurts too, don't have a nice rep piece yet, working on getting one from a friend of mind,
