According to my B+W pamphlet their equivalent of a #92 is their B+W 099
(Shcott OG 530). in the note the filter factor is approx 20-40
(repeat 20 to 40) which works out to between 4 and 1/3 to 4 and 1/3 stops
(Approx)..
Who is sitting hiping we do not get strong Chinook winds to blow all the
blossoms off the apple trees before the bees have had time to "do it" to
them "again" this year
