SG 210 10d Dull Purple & Carmine K39 (1) upper sheet marginal block of six in Post Office fresh unmounted mint condition. Please take time to view my other listed lots or contact me with any specific requirements as, like many sellers, I have large quantities of unlisted stock in many areas generally well below normal retail. In particular I have large stocks of certified Edward VII shades and varieties with many scarcer and unlisted ones particularly keenly priced. I believe I offer some of the best prices available and will always fully and correctly identify lots to lead to significantly higher offers than many who just skim over and offer as basic stamps, shades or varieties often costing hundreds of pounds on individual lots alone. Please contact me if you think you have material that is similar and may be of interest.
