Model tag query when ordering

Hi, I would like if someone could clarify for me what scooter model tags apply to my Vespa.

I own a Vespa Primavera 125cc from 1982. It seems that this model is tagged as VMA2T, and I think this is correct. Now, when shopping on the web, I need to match the item´s model fitting information with my model.

Many times what I see on the web for example: for Vespa 50-125/PV/ET3.

Sometimes I see: for Vespa 50 R/S/90/100/125 PV/ET3/150 Super.

Which tags are the ones that fit my model? ET3? PV? 125? Vespa 50-125?

And by the way, what is the model PV?

Many thanks
