I see SG has got their pictures mixed up in the Part 19 catalogue as both its "three palm trees" (type 50) and "one palm tree" (type 52) images show the the type 50 design (which also has a shaded background around the tughra unlike this stamp).
I do not have a copy of the shaded background, never seen it, and catalogues packed away. The later issues with Jet are interesting, having two different cartouches, of kings faisal and saud.
