UK Decca manufactured many records to be released by their London subsidiaries in the USA and Canada; as well as the "printed in USA" being a clue to this being a USA release, there is also the "product of London" statement on the sleeve and labels - Decca couldn't use their name in the Americas and Far East after WW2 because they had sold off their original subsidiaries (which became part of MCA, Inc. in 1962), so they created the London label and companies in 1947/48. On other US London releases made in England, you may also see "trademark registered US Patent Office", Library of Congress catalogue numbers, and mention of the RIAA curve, all details that wouldn't appear on UK releases. Plus, going by the 60's and 70's UK Decca catalogues that I have, they didn't use the Richmond label in the UK.
Record and inner sleeve are made in England, cover is printed in the USA.
In the Vinyl Album World there are several RICHMOND records, all made in Canada and some USA made.
So correct me if I'm wrong about the Country entry.
Never heard of it before, clearly a Decca recording (ARL 1331 and 1332)
