I don't have a picture, but what you have there will work with a HMMWV.
The black towbar feet are the MRAP/MATV feet.
The green 1.5"x3/4" feet are what hooks into the HMMWV. These are the same feet that come with the MTVR towbar and a 1" version exists as well. (2-1/2 ton, 5 ton, etc)
The tan adapters are the "biscuits" and hook into the towbar just like the black feet do, with the more rounded/triangular side towards the towbar. The HMMWV feet then pin into those to allow use with a HMMWV. (Or any other 3/4" pin vehicle, probably) The 1.5" pin with the bar on it connects the biscuits to the HMMWV towbar feet.
I've found that the MRAP/MATV 1.5" pins are too big for the other 1.5" pin trucks. I'm not sure what the adapter collar for the MRAP/MATV foot is for, but it made the pin size quite a bit larger.
Your kit seems to have a pair of MTVR 1.5" pins also, I'm not sure why. I don't know why there are so many different roughly 1.5" pins that don't seem to work with each other.
Too many acronyms!
Here are some pictures of the MTVR towbar -
