R9 (in Freeman's scale) is 7001 to 12000 ESTIMATED..... In the case of the F-169 and the F-164A (an R5, estimated 50001 to 100000), I believe that there are LESS than a dozen KNOWN of each, possibly as few as 8-10, although there has NOT been a reliable census mage on these in many years if at all, and the only census referred to repeatedly is from John Jerrams book on Victorian pennies and their varieties from 1860 to 1865, which sadly, with new discoveries, is out of date.....
