Verite Musicale rare vinyl gem

I got on loan this disc from my pal Enrico… it’s a 45 rpm recorded with a (Charlin’s?) dummy-head miking technique and the star of the disc is a 1716 gorgeous Donzelague’s harpsichord.
The disc is a truly seldom seen, sought-after wax, indeed… in same league than my beloved, Georges Kisselhof’s engineered Sarastro, also a 45 rpm disc, also a French production.
… but… BUT what makes this disc quite a rare breed, the back cover liner notes shows something unique: VM – Verite Musicale, the label itself shows an hidden sort-of “secret”!
The label claims the availability, for the discerning audiophile, of open-reel master copies of the superb recording, also offering different standards – i.e. 19 cm/s NAB/Dolby B or DBX and 38 cm/s CCIR/IEC with DBX noise reduction!

… something only Barclay-Crocker in the USA made… since the recent renaissance of master-dubs galore from several sources, as per my friend River Yu’s cool directory.

A nice find, indeed.
Thanking Enrico for the opportunity.
