ताण्ड्य महाब्राह्मण / पञ्चविंश ब्राह्मण (सायण भाष्य एवं चिन्नस्वामी शास्त्री टीका सहित)

'ऽ' followed by 'व' (or 'वै')!
Line 19: "ऽव उत्सृष्टाः स्म इति ऽवत्सानपाकुर्व्वन्ति प्रातः"
Line 20: "पशुमालभन्ते तस्य ऽवपया प्रचरन्ति..."
Line 22: "...श्चरुणा ऽवैश्वदेवेन..."

Wait, why would line 19 have "ऽव उत्सृष्टाः"?
Because in the Samhita/Brahmana text, the editor/manuscript wrote "ऽव" (for श्व, where ś was dropped or read as avagraha, or representing a variant reading / pronunciation!).
Regardless of the phonetic/editorial reason, visually it is unambiguously:
ऽव !
Wait, could it be ऽव?
Let's look at line 19 again:
Yes, it is ऽव उत्सृष्टाः स्म इति ऽवत्सानपाकुर्व्वन्ति प्रातः.
Wait, let's transcribe faithfully what is printed on the page!
If it's printed as ऽव, we transcribe ऽव.
Wait, could it be इव?
Let's compare the first character of line 19 with the 'इ' of "इति" in line 19:
'इ' in "इति":
Top has a horizontal line (shirorekha), then a vertical tick, then an S-like curve, then a loop
