Peter,
For a number of years C. Plath made their sextant handles just as this one is, with no back cover and no provision for lighting. This design permitted the sextant, when lowered into its box, to be pushed down to engage two leaf springs in the base of the cradle. Those leaf springs pushed the sextant up against the gate piece that swung across the top of the handle, helping that gate to stay in position across the handle. This handle is unfortunate in two ways. First, without a back half, it is uncomfortable in the hand. Second, this handle bisects the angle of the frame instead of being canted at an angle that allows for a far more comfortable position for the wrist of the user.

With Bakelite handles like this one, there is usually a C Plath imprint on its face. Some, perhaps all, of this era came in heavy black Bakelite cases with a variety of systems for holding the sextant securely. Maybe Negus had a box made or adapted another for the instrument.
