I hear what you say on that one. If possible I will always look for LPs that are 'pre oil shock/3 day week'. They are usually thicker and with 'virgin vinyl', not the recycled rubbish that the majors in the UK and US (honourable exception - Japan) used in the late 1970s. Comparing something like a Decca 1960s pressing and e.g. a Pye from say, 1976 is no contest.
