Yes I posted about the meat connection above the Boursicot Le Courrier post.You beat me to it mishy66. I had drafted a similar response as follows....
I am intrigued by the fact the Fredy David as RB stayed at 59 Dolphin Cresent Whale Beach. The house may now be in the Penney family ownership but in 1971 it was likely in the hands of the Le Boursicot family. Only 3 years earlier an advertisment appeared in Le Courrier Australien promoting M L Boursicot's Import / Export Business from the same address. Since 2000 the Courrier Australien has been co-owned by a very reputable member of the Le Boursicot family BJY Le B. That family was also in the meat packing business just as the DDH's Walker family WAS, and possibly with links MJR (the butcher) as an alias for RB. Was Fredy David possibly scamming the Le B family, forming a partnership or perhaps just a family friend. Both RB and MLB mentioned they were polyglottes in their advertisments.IMO
I am not so sure now that RB was MJR....just going on what the MB FB page has revealed - J having been in contact with him and the documents I unearthed some time back.
I am now thinking that MJR worked with the company owned by RGW....
