- Entry 10: พรมณี in Mueang Nakhon Nayok district, Nakhon Nayok. Seems like the spelling has changed, since the subdistrict is now named พรหมณี (Phrommani), or it was a misspelling in the announcement, forgetting the Ho Hieb (ห) which only changes the tone of the second syllable.
- Entry 49: หนองโพธิ์ (Nong Pho), Photharam district, Ratchaburi province, is now spelled หนองโพ - the anyway silent last syllable no longer written.
- Entry 28: ไก้จ้น (Kai Chan), Tha Ruea district, Phra Nakhon Si Ayutthaya province. I now could find that this is in fact the subdistrict Tha Luang (ท่าหลวง). I even already had processed the announcement which contains the rename, but in that the subdistrict is spelled ไก่จ้น, a different tone for the first syllable. But since it is a different spelling it did not show in the search. I have no idea if the spelling was changed as well between 1958 and 1961, or which one of the the two announcements has the spelling mistake.
Other types of state-led local administrative bodies such as 71 PAO, 585 sanitary districts and 59 units of TAO during this period (the number is as of early 1970s).But, there were 59 entities created in 1958, and one more (Ban Chiang, Nong Han district, Udon Thani province) in 1966, so it would be 60. Don't know which number I should believe, if there's anything not published (or not yet found) in the Gazette I am missing here.
Anyway, a small statistics of the distribution of these TAO show that only some provinces had TAO created then. Sorted by number these are Ayutthaya (11), Surat Thani, Ratchaburi, Nakhon Si Thammarat (6), Nakhon Sawan (5), Chachoengsao, Chiang Rai (including Phayao) (4), Nakhon Ratchasima, Nakhon Nazok (3), Sakon Nakhon, Lampang, Phuket, Phichit (2) and Yala, Phetchabun, Khon Kaen and Udon Thani with one. Thus by region it is 24 in central Thailand, 15 in the south, 14 in the north and only 7 in the north-east.
Of these 60 TAO, 5 are now municipalities after being recreated as TAOs in the 1990s:
- Ratsada (รัษฎา), Mueang Phuket, Phuket
- Pla Lo (ปลาโหล), Waritchaphum, Sakon Nakhon
- Thung Luang (ทุ่งหลวง), Pak Tho, Ratchaburi
- Chun (จุน), Chun, Phayao (then Chiang Rai)
- Bang Wua (บางวัว), Bang Pakong, Chachoengsao
- Maret (มะเร็ต), Ko Samui, Surat Thani
- Lom Raet (ล้อมแรด), Thoen, Lampang
- Pho Hak (โพหัก), Bang Phae, Ratchaburi
- Don Tako (ดอนตะโก), Mueang Ratchaburi, Ratchaburi
- Tha Chang (ท่าช้าง), Nakhon Luang, Ayutthaya
- Bang Pramung (บางประมุง), Krok Phra, Nakhon Sawan
- Kao Liao (เก้าเลี้ยว), Kao Liao, Nakhon Sawan
- Chan Chawa (จันจว้า), Mae Chan, Chiang Rai
