Steve,
Not only did the Cambodian AF and the VNAF fly the Provider, but the Royal Thai Air Force operated them for many years too.
As well as South Korea, Saudi Arabia, Laos and the phillipines not to mention a couple of private firms like Butler Air Services and Air America. There are plenty of schemes available to do, thats why i'll be uploading the layered paintkit incase anyone wants to do any of them :d.
