Here is a link to a Rogers 89RS spray shielded tube.

Here are pictures of my Rogers 6G7S tube which was the direct substitute for the 89rs. Also there are pics of service manual notes for the Rogers R-371 radio chassis. The 6G7S tube was used in production as of Oct, 1, 1934. It is a 7 pin pre-octal tube.

Additional info: Rogers got a US patent for a machine used to spray shield tubes. Here is the link.
