Is this a statue of a six-armed wooden Buddha? Please help me identify this statue. Thank you!
"Buddha statues generally show a particular Mudra (a Sanskrit word) or hand gesture."


~ Cited from: Buddha Statue Mudras


Bhumi Sparsha Mudra
Samadhi / Dhyana Mudra
Abhaya Mudra
Dharma Chakra Mudra
Vitarka Mudra
Vajira Mudra
Uttara Bodhi Mudra


Apart from the above listed Mudras there can be a combination of two Mudras or a variation of a Mudra depicted in a statue of Lord Buddha. For example the below statue of Lord Buddha depicts a variation of Abhaya Mudra.

Since the statue you've shown doesn't depict any of the known Mudras, there is a high possibility of being that is not a statue of Lord Buddha.
