There's a sticker on the box that says 'Ecopla', and I've found that's a range of Bandai kits that use only one color. Also, the use of 2 colors of plastic on the same sprue (black and dark blue, it turns out after inspection in decent light) suggests the sprue was made on a machine capable of moulding multiple colors, not the low-end machine I'd expect a bootlegger to use.
