Chrome's second release also had a variety of inserts, as well as some exceedingly rare promotional materials.

It appears that the first insert (the story of Pat Stevens) seems to have been included with most if not all of the Siren releases.  Some of them have the text "THE STORY OF" added with a rubber stamp, others do not have the stamp.  The second insert was in a copy that Paul H. Williams purchased back when it was released.  (Above inserts from the collection of Paul H. Williams.)

Both the Siren and Expanded releases were issued with an inner sleeve with lyrics, credits, and a cool picture of the band playing.  The later re-releases did not have this inner sleeve.

The Siren pressing has been released with black labels (grey text)  and with white labels (black text).  There are also heavy-weight vinyl (165 grams) and lighter weight versions.  My copy has the black labels and is on the 165g vinyl.  It appears the that white labeled versions are of a more typical weight (115g), although there may be exceptions.
