Change of area of Muban in Ubon Ratchathani

Today, the Royal Gazette contained an announcement which changes the boundaries of Ban Na Chumchon (บ้านนาชุมชน), Mu 8 of Sai Mun subdistrict, Phibun Mangsahan district, Ubon Ratchathani. The actual boundary change is probably just minor, the announcement doesn't mention the change and just lists the new boundary. What is interesting however is that the announcement refers to the old boundaries by mentioning that the administrative village was established on May 2 2001 - shortly before the Muban creations were published in the Royal Gazette. Thus this village is now one of the very few where I know the date of its creation indirectly. Sadly none of the ministerial orders on the creation of Muban, especially none so old, are available online, those would give a lot more data to add to my XMLs.
