Not sure Greg is doing this anymore. Really haven't heard from him in awhile. I would think sourcing something like this should not be too hard. More and more people have CNC machines. If anything it may be a copyright issue. Wish I could help more.
I had a local guy in SoCal etch me this using a material called Alluvium since I did not like the boring N420 plates its came with. He can etch whatever you want. If you are interested DM me I can give you his details.
