Hello John K.,
Thank you very much for posting that paragraph
listed in the book regarding the scanty information
available on that outstanding specimen once owned
To further back up the paragraph I believe I've found
an actual photograph of that exact specimen.
I have seen its photograph reproduced at least 2x in
Guinness record books. Once in a late 1970's edition
(posted here in my first photograph) with corresponding
information below the photo; and a second time in a
1985 (hardbound) edition with a (larger) picture and similar
information likewise noted.

My own personal thoughts on this mammoth specimen
are that Oberthur likely sold this specimen to someone
with money before his health went downhill. He was after
all a dealer on a big scale in his time.
It may still exist out there but, like rare, older automobiles
of low production or pedigree it has probably seen only 3 or
4 (owner/caretakers) since the Oberthur collection was sold
off and broken up in 1927.
And again, smart collectors REMAIN discreet about personal
"special things" which they have acquired; rather than advertise !
