Matheson 8-320 Regulator help

Hi all,

I bought a Matheson 8-320 CO2 regulator on ebay and i'm having some trouble identifying the connectors coming out of it. I've read online that it can either have the 1/4" NPT connector or a weirdly threaded monstrosity that requires an adapter of some kind. Is mine 1/4" NPT or the other?

The pictures are as follows:

1) the regulator itself
2) the part that goes to the tank - what is the white plastic stuff capped inside? is that a stopper that I have to remove?
3)the low pressure output side - is this 1/4" npt?
4)a valve that came with it that was in the low pressure output - I removed it.

Help me plantedtank forum, you are my only hope.
