Gray,
Did you find a RB map? If not, here is what I have.
It is a map that I originally mounted on foam core board. I then treated the map with a waterproofing agent called Mapseal. It worked great except that when it dried, the paper shrunk just enough to cause the foam core to bow. At the time, RB maps were available from MMP, so I ordered a new one. Eventually, I carefully removed the map sheets from the board. This procedure resulted in a small (1-2 inch) tear on one end. Otherwise, the map is fine. I recently pulled it out to look at it and was surprised to see how good it looks.
It will require the use of plexiglass to lay it flat, or you may be able to flatten by laying it out with some weight.
So, there it is. If you are interested, I would be willing to send it to you at your expense.
