Almost forgot to elaborate the Kamfa and the KGM part. KGM came from the old school classic Kamfa. But to my understanding, the modern Kamfa came from KGM itself.
KGM was bought by Thailand breeders, they crossed a KGM x Thai Siam ZZ x Kamfa and created their own KGM aka Thai KGM. Although they are much more difficult to create through a few generation of inbreeding and selective breeding. As far as modern Kamfa goes, I don't know exactly what they used to create the modern Kamfa but I know that it is created in Thailand using a KGM.
