Fomapan make less of a range also - five products (Fompan 100,200,400,R and Retropan). vs Ilford's ten (Pan F, FP4, HP5, Delta 100,400,3200, XP2, SFX, Kentmere 100, 400)
Both, Harman and Foma make more products than just consumer films. Both make also consumer halide paper. Harman also cosumer ink-jet paper. and bot are active on the non-consumer field too.
And even if they both only would make consumer films, I do not see what relevance the number of type of these has on their size or revenue. It may though have effct on profitabilty, as with growing number of products the internal fixed costs grow.
