I have a copy of Jethro Tull's Aqualung and it would appear to be an early press; the vinyl is really quite heavy, the cover is matt well put together, and I bought it second hand with the supporting tour guide (of the aqualung tour with Steeleye Pan). So it's not inconcievable to assume it was bought at the same time.
Anyhow the problem is that the matrix numbers are a bit odd. The label has:
on the A side, and the same on the B side with a B instead of an A.
However on the wax itself, says
ILPS.9145 A-1U & ILPS.9145 B-3U
but these values have a been scratched out and replaced by:
CHR1044 A-1U & CHR1044 B-3U
Which are written by hand rather than stamped.
I am just curious to know what has happened here.
