It is hard to tell how names and notes were applied to particular images but often times they were done to the negative themselves which would still make them "Type 1" images. If black paint was applied to the negative it would show up white when the photo was developed and white paint would show up black. Etched names into the negative (scratched on them backwards) were crude but were often done and also pencil was used by many photographers such as Charles Conlon where notations would show up on the side. With photos in hand you can generally tell from the clarity of the image whether they are off the original negative. If the image is clear and bold with small details visible such as individual blades of grass etc. it is highly likely that the names and notes were added to the negative and not afterwards making it still a "type 1" image. Each photo should be looked at individually as there is no blanket rule regarding notations and identifications and the type system.
