Maybe this is what's being discontinued. I don't think the stick is called Classic, but I could be wrong

I'd bet that is it. Arko shave soap is used by about 95% or more of Turkish barbers. It would make no sense to discontinue it. Probably a false alarm.
Even if it were to be discontinued, Camelot is very similar and would suffice.
