The question is; was this a dry run practice for the later film or was it a deleted scene from the promo.
I believe it to be a deleted scene. It didn't match the documentary style nature of the promo and was almost laughable in it's setting and mood with the butler. In the actual promo, his real personal assistant was used as well as his secretary, posse of actors and other workers.
It is so nice to see something new on Chaplin over 100 years old.
