Our experiences have been somewhat opposite:
I cannot count the number of Montblanc boutiques I have been into and asked for a bottle of Hitchcock ink!
In the year of its release, I was touring the UK and Europe and it became a 'thing' that I would call into a boutique and ask for Hitchcock, in every new location we visited!
I still do go in and ask, if I find a boutique I've never visited, before.
And yet it is one ink I have never managed to attain! (Dare I say "yet"?)
Best wishes, CS
Thank you for explaining your own experience with seeking Alfred Hitchcock ink.
It is the first purchase I ever made in any Montblanc boutique.
I'd never heard of it, or anything else from Montblanc, when it was offered to me as the only available red ink.
Without your explanation above, I'd never have realized how fortunate I was.
I hope that someday you'll find a bottle.
