804 Hing Wai Building
US Office registered as C0538685, current status is 'suspended'.
Very Little is known about this company at this time, from the extant sample (jobbed in 1966) in the authors collection and the title, it seems clear enough that HKMC were a marketing co-operative for several smaller, probably nameless or Chinese-named Hong Kong toy makers. They registered a US office/partner in 1968 under California's due restriction, whether this means they concentrated on selling to Western US sales territories or not is too-much speculation!
The address of the company has also been demolished and replaced with a taller building also called Hing Wai.
Known ProductNH 706/211 - Soldier Tank and Jeep (four Lido 54mm copies and crude sub-scale wheeled tank, salesman's sample, may never have been retailed)
