Hi Jack the wheels are made down here in Aus in Sydney, 3 piece alloy with a billet cnc'd center and very reasonably priced, and bloody light too for a 4mm barrel.
Leon yeah considering I bought them blind I reckon I hit the jack pot, I really had my heart set on the pin drives but it wasn't meant to be, but i'm more than happy with these, I reckon they will set the ole girl off nicely.
cheers John
