No delusion....I have several #89B's in stock in this Cokin-P 
size....US$30 each....also a bunch of "#87C", but those are IMO not 
produced/colored correctly, and appear to be lighter than 
my other #87C references....about #88A I would say.
Note that Ilford SFX200 (and its Teutonic equivalent Agfa APX200S) 
can even be mastered with #87 and #87C, as long as you take veeery 
long exposure times in account....we are talking single-digit and 
even fractional-ASA area here....
