Beeman Technical Bulletin 8215 and 8217

Was looking around the Internet at pictures of Webley Hurrican's and found a few pictures of what appear to be later ones with these two bulletins as a part of the paper work they shipped with.

Does anyone know what they were for?

{Edit] Never mind, I found that the one I have has the same bulletins only in a different format where the numbers are in small type and I didn't notice them.
