Crossword editor’s update: are you the mystery setter Pendorne?

I’m on the hunt for the pseudonymous writer who penned a bespoke puzzle for a reader. He or she may well be reading this article …

In February, this clue appeared as eight down in a puzzle from Tramp:

8d Guessing John, finally is eighty: posh spread? (13)
[wordplay: anagram of last letter of (“finally”) JOHN & ISEIGHTYPOSH]
[definition: guessing]

My family are apparently arranging a tea party for my significant birthday in March, and it seems that your crossword setter Tramp has got wind of this. This is shown by a clue in the puzzle on 14 February: “Guessing John finally is 80: posh spread?” As for the solution, I’m hypothesising that Tramp is not only an excellent setter, but has great powers of clairvoyance too!
