Well, just to bump this old thread, I have just returned from a road trip to Loei where the above plane is situated. I hadn't been there for about eight years. The public park turned out to be a bit of a war memorial and strangely (for Thailand) there was a bit of activity going on in regards to maintenance. Here are some pics from just the other day. Also, for those interested, they also had another war plane in the park, I believe that it may be a Trojan.
