After finally getting a chance to look at the box I think I was right that this is a Hasbro US reissue. There is no info for Hasbro HK on the box but there is the standard Hasbro US info of Australia, UK and NZ addresses on it.

Mine's paint is perfect and no swapped parts, but the joints are terrible. This mould has been used too many times. My 1st run Takara MP-8 has much better joints than this the most recent use of the mould.
