RSTS-11 distribution?

I am looking for RSTS-11 circa 1972 to install on my PDP-11/10 machine. I am more interested in a "historically correct" rather than "more useable" system. I have a PDP-11/10 with 32kw core memory and an RK05 disk drive. My goal is to load RSTS-11 on this machine. I have scoured the internet, including rsts.org and Bitsavers, but I have not come up with an installable distribution. My plan is to use Ersatz-11 or simh to prep a virtual RK05 disk. When I am happy with the setup, I will transfer the binary disk image to my real RK05. I wrote a program that allows a binary disk image to be transferred via a serial port (I will release the source once I am successful in getting the machine running). My hope is that I can find a distribution (virtual tape, virtual disk, etc.) that I can use to install my OS. I am looking to learn and understanding the process so that I can become self-sufficient. Any ideas where to begin? --barrym
