Thanks so much @boojidad ! This is why I love this place, between us all we're filling in all the blanks with stuff like this, and we all get to share in the knowledge. I think that Acker Bilk tape may be the very last Pye Q8 that Precision Tapes released, at least numerically speaking.
I actually recently got my hands on a 1976 issue of the Record Mirror Tape Guide (the same one I posted a picture of the 1972 and 1974 issues earlier in this thread) courtesy of the magnificent and resplendent @fredblue , and it actually contains listings for both of the tapes you posted and I wondered if they actually existed - your picture post leaves no doubt. 1974 must be the final year that Precision Tapes did Q8s and the tapes from that year seem to be rare as hen's teeth, sort of like the '77 Columbia Q8s, but maybe even moreso, to the point that you wonder if some of them were issued at all.
My plan is to go through the 1976 Tape Guide in the next few days and add all the Precision Tapes Q8's that aren't already listed in the table in post #1, and I think at that point we'll have a pretty comprehensive overview of everything that they released.
My longer term plan is to start a new thread that features scans of the '72, '74 and '76 Tape Guides and also to a 'master list' of everything released in quad in the UK, culled from those three catalogs in addition to Mark Anderson's discography etc. I'll use that info to update the various label threads I've done already, like this one, the EMI UK one, etc. The Tape Guides are also useful because they show what was released in the UK by the American labels, including CBS, RCA and WEA - although none of these labels released anything unique in quad in the UK (save the 3 or 4 Warner UK CD-4s from 1976) I think that'll be the first time a comprehensive overview what they did issue in quad in the UK has been available anywhere.
