harimauhk,
Ooops, guess you saw my comment before I edited it...Hey I've had some good laughs to from others when I struck a deep kung fu pose in front of a Taoist temple :P but hey you got to have fun posing...
Yes, I think this is one of the better made daab in thailand. Some Thai forum members like Puff might be able to say more than I have about the smith, etc...
I thought of another forum discussion which might be of interst...you can see an earlier model of the Lampang daab:

Also if you look on ebay there is another Lampang daab...not by the same seller your bought...but another seller from Bangkok....
