SG 399 2/6d Deep Sepia N63 (2) Waterlow Seahorse in very fine and very fresh lightly mounted mint condition.

This the stepped, deeper and far scarcer shade than the SG 400 listing many sellers 'confuse' it with so conveniently.

No substitute for checking, as always done here, every single stamp listed against extensive shade reference collections to keep that accuracy of identification paramount every single time.
