I am gradually selling my collection of 37 years but given the eBay selling limits, this will take me some time. I have over 600 controls and cylinder blocks to get rid of.

GB QEII 1981 4p Greenish Blue. SGX997. Cylinder number 8A7B dot. MNH block of 10.
Unmounted Mint - please see photos before bidding.

I will happily combine postage for multiple items so long as the new eBay posting rules allow me! Please request an invoice if I haven't already sent a combined one.
