This is the same batch as the renowned 2515 Wat Bang Klang batch ceremony co-joined with at least 6 other temples with almost identical Rooplor Phor Ngern.
Of course, Wat Bang Klang's pieces, being the temple of Phor Ngern Himself, is very very expensive even till today and fakes runs amok.
The more affordable ones are from Wat Moonlek and this from Wat Tha Bua Thong.
Phor Ngern is believe to gives strong protection and because Ngern also means wealth or monies, it is also believe to bestows wealth to worshippers. This belief is held strong till present days and I'm one of these strong believers and also been experienced by many devotees.
