My apologies if I led anyone astray at post #5, but it seems most have finished with no problem.
Les & Aristo set me straight on 19D.
Les was correct about "names of signs".
Excuse: Too little fill at that point & too much pain (back problem) to think clearly, e.g.:
20A got me on the wrong tangent. Here's what happened:
Had P?L?ROW leading to PALTROW (Gwyneth ?).
The "T" fit with what I expected for 8D QUINT???
"
Read the signs". So I
did & applied my massive brain power to arrive at this.
ΒΆ looks like a backward "P" with a bar, ergo:
P + ALT (reversal) + ROW (line)
"
What? Ya gotta problem with dat?"
I certainly did, trying to relate the other clues to someone similar.
Sign references: Ch = Cambers, NOAD & CX = NA & CA Oxfords
W = Wikipedia, (W-R) = redirect, (W-S) = separate entry
1A NOAD, W-R
20A Ch, W
22A none, W (smaller than a Bullet) U+00B7 vs U+2022 (Unicode)
37A none, W
51A Ch ? (weird math def.), W-S
8D all, W-S
26D none, W-R
36D all, Ch, W (Ch does not show that symbol)
Minor quibbles:
Unchecked "C" at 20A & 8D cross.
"
Read the signs". What does that mean?
Also, Wendy has participated before, & welcome back.
I'll post an unofficial solution in a few days, to give everyone a shot.
