That's the only right angle "Hirose" that exists (afaik) and it isn't manufactured by Hirose, nor do they make a right angle connector.
Unfortunately I'm not at home, otherwise I would just take a picture. How you select the angle 12, 3, 6, or 9 o'clock) was horribly designed. A little teeny tiny metal tounge and groove holds it in place, until you use any amount of normal force and twist the input connector it's easy to rotate the position, which in turn kinks or strains the conductors, which can potentially cause a short.
These things are fine if you never intend to touch it, but when I put my 744T in a gear bag already crammed full of gear it becomes all to easy to accidentally twist the power connector.
With a genuine straight connector, there is zero risk of this occurring.
