Sorry, it never made it into cyberspace. I built it while I was redundant so couldn't afford a host and then this site sucked me in and enabled a lot of the content of my site to be used here.
You cannot safely say that the one without the ® is the earlier issue (although the vast majority will be - first pressing is a pointless term as several presses would have been used simultaneously) as there is the possibility that any repressings after June 1976 may have been on the old label stock. There may even be mis-labellings like your Mountain Grill,
This might be quite useful - taken from a web site I built a few years ago:
The United Artists label from a Hawkwind collector’s perspective.
In 1968, Transamerica Corporation, an insurance conglomerate, purchased Liberty for $38 million and combined it with another of their record companies, United Artists.
In 1970 United Artists merged with Liberty Records to become Liberty/UA. This change can be seen in the label rim text of the blue and black label versions of LBS 83348.
Liberty was shut down in 1971 and Transamerica released all new singles and albums by the Liberty artists on the United Artists label.
In America this transfer corresponded with the 1971 single "Tongue In Cheek" by Sugarloaf (Liberty 56218): in the UK the latest single I could find was “Why I Sing the Blues / Jed Collder” by Cochise (LBF 15460) and in Germany “Light / Lemmingmania” by Amon Düül II (Liberty 15468), both also from 1971.
Hawkwind’s next appearance on vinyl was on the "All Good Clean Fun" compilation from 1971. This issued a track from the Liberty LP onto a release on the new label. The label rim text ended “MANUFACTURED IN ENGLAND. A PRODUCT OF LIBERTY-UNITED ARTISTS RECORDS LTD".
A major change took place around June 1976 when the ® appeared after the UA logo.
According to a history of United Artists, in 1978 UA executives bought the record company from Transamerica with a loan from EMI. The name of the company was changed to Liberty/United Records and the UA Records name was retained.
However, looking at the evidence of the record labels, the next change of wording occurred around November 1976 when it became "MANUFACTURED IN ENGLAND. A PRODUCT OF UNITED ARTISTS RECORDS LTD".
Sometime in 1979 the label text changed again to end "MANUFACTURED IN ENGLAND. A PRODUCT OF LIBERTY-UNITED ARTISTS RECORDS (UK) LTD". This variant did not exist for long.
In 1979 EMI foreclosed on Liberty/United Records and the label name was changed back to Liberty in 1980.
Finally, in 1980 both the UA and new Liberty labels were printed with the text ending "MANUFACTURED IN THE UK BY EMI RECORDS LIMITED".
These are not definitive dates as there are many examples of old label stock being used after the transitions.
