I'm sorry I can't share Brendan's enthusiasm for this puzzle. I'm not familiar with Tramp as I mostly do Times crossword books, preferring their uniformity of style, but I've begun to branch out a bit during the pandemic. Paul is my favourite setter, so I don't mind liberties being taken, especially in aid of a good gag, but this puzzle defeated me -
5d is given only as a type of salamander in both Collins and OED. I don't object to obscure words, but feel they ought to be widely referenced. It would have been fairer to clue the widely referenced amphibian rather than an alternative meaning which only appears in Chambers.
19a is not a type of tea, nor 22a a kind of armchair, in the same way that 'walking' is not a sort of stick. I was familiar with the tea, but not with the American slang 'rod', which seems very obscure. 22a clues American for the letter A, this is not a common abbreviation, I've not managed to fine a reference for it in Chambers (online).
23d 'see' as the phonetic spelling for the letter seems fine, but I'd not come across it nor can I find a reference for it.
Sorry for the negativity. The crossword is cleverly constructed, but with some minor changes it would have been a lot fairer.
