SG 418 1/2d Green N33 (1) 1924 Watermark Block Cypher D 25 Imp Control in Post Office fresh unmounted mint condition.

Stamp and control selvedge free of mounting or marks here to justify the Post Office fresh prefix.

Remember any list prices seen are merely for mounted mint copies and many who will offer unmounted mint at a premium when the very thing that attracts the premium, the control, is that which bears a hinge.

Full UK postage and packing included here as has always been the case, just happy to try and help you build your collections at minimum costs.
