Galerie was unique in having only minor drydown shift, and in remaining neutral black when selenium toned, yet with the density enhanced. It had been around a long time; and I last used Gr3 maybe 6 yrs ago, when it was already quite
difficult to acquire.
Compared to their MGIV FB, Galerie Graded really was a premium paper. But I actually got better results from Harman Fineprint VC FB (now gone too), as well as from present MG Cooltone and certainly MGWT. I'm not quite as much a fan of Classic, but have certainly gotten good results with it. So even if Galerie was still around, I probably wouldn't have any reason to buy it.
I began using Galerie long ago, but never did adopt it to the extent I did the original Oriental Seagull G paper or Brilliant Bromide, or even Agfa Portriga. Ansel Adams was addicted to Galerie, though I didn't care for the slightly greenish cast his parallel addiction to Dektol lent it.
