SG 279 1/2d Dull Green M4 (1) A 11 Control in very fine and fresh lightly mounted mint condition with partial hinge top fragment remains to upper reverse.

Like the large majority of this Perf 15 issue, it has some small element of bluish to the shade and this can of course be magnified or mitigated depending on what you are comparing and contrasting it with.

Here of course everything is compared and identified fully in conjunction with a very extensive and time-tested reference collection assembled over some 50 years of collection and collaborative study.
