Retineam o informatie citita mai demult in cartea recordurilor (acele fascicule aparute intr-un ziar prin 1991), am verificat din nou, si acolo se face referire la aceeasi luneta prezentata la expozitia de la Paris in 1900.
Probabil acolo s-a strecurat o gresala in privinta diametrului obiectivului, s-ar parea ca in realitate a fost ceva mai mic de 150cm. Insa refractorul nu a mai fost folosit deoarece "nu a fost reusit". 

Pentru cei interesati - un top 9 al celor mai mari lunete construite:

PS. - continuarea citatului de mai sus:
...After several adjustments, the instrument could have played an important role in research, but it was unfortunately dismounted and its components were sold.

Situatia parindu-mi-se mai interesanta, am mai gasit o sursa:
1900 Paris Exhibition telescope. Two 125 cm objectives visual & photographic 900 kg each, cast at Mantois. Fixed 60 m tube. Mercury floated siderostat; with 2 m mirror, cast at Jeumont, ground & polished by Gautier over 10 months. Gautier designed & built polishing machines for optics, built thermally insulated workshop with double walls. Telescope used at exhibition by Antoniadi, but failed due to lights & smoke, unventilated steel tube; also only photographic objective was completed & used visually & photographically. Financial problems after exhibition, telescope later scrapped, siderostat mirror now at Paris observatory. Large financial loss from this telescope ruined business.
Competitia cu America, inteleg sa fi produs motivare, dar cu ce scop si pret?! 
Acum reiese ca obiectivul ar fi fost bun, dar practic inutilizabil.
