747-100B: Reinforced structure, later-series JT9D engines, options for
several series of GE CF6, Rolls-Royce RB211, previous features of
already existing 200B, allowable taxi weight increased to 753,000 lbs.

Japan Airlines , Saudi Arabian , Iran Air (initial customer), only
customers identified as buying 100Bs.

Given small production, that 200B already in production, does seem a
bit of an oddity.
