Where would I go about purchasing the rig/belt (sorry, idk what

Looks like either bandoliers or just Mauser ammunition belts that they threw over their shoulders.

Pretty sure it is bandoliers though i also want more info.... Saffer bumping for more info

Any sort of leather mauser Bandolier will do. The Swedish Mauser ones tend to be undamaged and online, though quite expensive, you could also look into old British gear like the P1903 webbing.

New ones also cost a bloody fortune... But thank you very much for the info

If historical accuracy isn't paramount, you could just slap a bunch of 60 years old East German ammo pouches to a belt at 4€ a pop and call it a day.
