Oh, if you mean is the SSPV another ***TRULY ROMAN CATHOLIC SOCIETY OF VALIDLY ORDAINED PRIESTS***, yes it is along wiht the CMRI and many other independent Roman Catholic priests!
:-)
I gave a brief pedigree, for those unfamiliar with the SSPV, but here is a bit more. In 1983 although Abp. Lefebvre still permitted the SSPX priests in Australia to use the unadulterated pre-Bugnini rubrics of the Mass, i.e the Saint Pius X rubrics, he forbade the SSPX priests in the U.S. from continuing to use them and ordered them to switch to the John23rd rubrics. Nine priests refused and he expelled them.
They then formed the SSPV which later fragmented in the early 1990's over the issue of whether the Holy See is vacant or its authority and occupation merely impeded.
Bp. Dolan, Saint Gertrude the Great

And not connected to them but they are good Roman Catholic priests and I'll post them also:
Congregatio Mariae Reginae Immaculatae

There is also the Istituto Mater Boni Consilii, an independent order of former SSPX Roman Catholic priests based in Europe and headquartered in Italy.
