Here's an article that sheds more light on the subject. You're right, i believe the name "Silvertone" wasn't used to re-brand guitars until the late '50s. Stella was popular in the early 20th century because of its affordability. I see 'Acme' listed in the one page shown from the early S&R catalog.
