Both my 28 (1895) and 27(1907) are like that, while the 127 (1922) and 128 (1925) are not.
And yes, the attachment sets for the older machines are very different, and for the older ones, they didn't come in the green cardboard boxes either. I think Singer went with the green boxes around the same time they went to the green manuals (I believe around 1913).
