Missing TAO announcements

Another part of the missing Royal Gazette announcement series, this time for the TAO. While working through the 6781 TAO creations since 1995 and cross-checking them with the list of TAO and municipalities (thesaban), there are a few cases where I could not find the complete history with my sources so far, so either it wasn't announced in the Royal Gazette at all, or the announcement is for whatever reason not be found.

• The first one I already mentioned when I compiled the complete list of local government units of Surat Thani - the creation of TAO Bang Kung (องค์การบริหารส่วนตำบลบางกุ้ง) was announced in 1995, however that area was also added into the town Surat Thani in 1994. Either the abolishment of that TAO is missing, or it was a mistake to list it in the creation announcement.
• TAO Wiang (องค์การบริหารส่วนตำบลเวียง) in Phrao district, Chiang Mai, was created in 1997, and apparently it was included into the subdistrict municipality Wiang Phrao (เทศบาลตำบลเวียงพร้าว). But all I could find about that was this listing, which suggest that the merge was done in 2000 - which I could not find in the Royal Gazette yet. However the addition of TAO Thung Luang into the same municipality in 2004 was announced in the Gazette.
• The rename of TAO and subdistrict Plueai (เปลือย) to Hua Chang (หัวช้าง), Suwannaphum district, Roi Et, maybe in 1999.
• In Nong Song Hong district, Khon Kaen province, two TAO had a different spelling in the announcement on their creation than they have today. For Khuemchat, the (silent) final i is left out, thus คึมชาดิ changes to คึมชาด; for Wang Hin (วังหิน) it is spelled Wan Hin (วันหิน).
• In Kalasin, the TAO Non Sila Loeng (โนนศิลาเลิง) was announced with the name Non Sila (โนนศิลา), however I cannot find anything about a rename.
• TAO Nong Yai (หนองใหญ่), Chonburi province, was apparently merged into the municipality Nong Yai, but no announcement on this.
• The TAO Samrong Phlan (สำโรงพลัน), Sisaket province, was announced by the name Samrong Phlap (สำโรงพลับ), and no notice on a rename of the TAO. Another TAO of Sisaket, Pa Ao, changed spelling slightly, a silent R has been left out, so ประอาว became ปะอาว.
• In Phra Nakhon Si Ayutthaya, the TAO Bo Ta Lo (บ่อตาโล่) is spelled Bo Ta So (บ่อตาโส). This is most likely a misspelling, the tone mark changed the letter L into a S.
