note subject frame's double chainstay stop
this is a helpful dating aid
both Juy & NERVEX offered this fitting
the NERVEX is Ref. 872 or 872bis
given caliber of frameset and presence of Juy endset it is likely to be intended for the Juy 543 gear mech:

the companion front mech at this time may well have been one of the Juy manual ("suicide") front models such as the Competition or Randonneur serie

the frame's Juy dropout set is a variation of the model Competition Ref. 934 935 made without gear hanger, introduced about 1951; if fork ends a match they shall be Ref. 932 933
here is a manufacturer illustration of the model with gear hanger, do not have a catalogue illustration for the variant without gear hanger

have never seen a Paramount fitted with Juy ends and mechs but that certainly does not mean none were ever produced given that customers could order framesets/cycles bespoke
our Paramount experts are sure to know...
@ccdc.1 will definitely be able to enlighten

presence of Campag R/NR headset -
think this to be a klinker as a great many cycles were produced with Campag gear ensembles and non-Campag headsets whilst precious few to none with Campag headsets and non-Campag gear ensembles
TTBOMK Campag never produced a dual cable rear gear mech
---
Geminiani suggestion -
there never was a Geminiani bicycle company or factory
all machines bearing the name were contract produced
they came from several makers; by far the greatest fraction issued from MICMO (Gitane, Helyett, Roger Riviere, etc.). some of the high quality models were done by Cizeron. there were also a few produced in Italy; Chiorda was a maker of some of the lower end examples.
