I chanced upon them in some provision shops. One of the brands is Super Heroes and the other is I.Q.
Next is War Machine Mark II and you will realise the color is way off. It should be gun metal black and this color scheme was Mark I. Furthermore, there is no shoulder canon and so what you see here is a very rushed modification made with whatever parts they provided. I have to recolor the additional parts as they came in gold. The face plate provided was gold too but I was lucky that the face plate of Midas (below) came in silver and so, a quick switch does the job.
Finally, Bones here is almost correct except the hands came in flesh color and so black markers will come in handy.
