I've heard of the Huff papers too, but haven't been able to turn up anyone with copies of them. I have some notes somewhere on G. flavivulgaris breeding and G. major breeding. There are enough similarities between the various Gerrhosaurs that you can probably follow the basic breeding protocols and have some measure of success. Let me know if you want copies of the info I have and I can forward it on to you.
