Postal Stationery: REGISTERED envelope 8 1/d Size F: Up-rated with 6d coil stamp
The Post Office sometimes created coils to make the up-rating of "old " stock more practical.
Some of these coils were not intended for public sale. ( Interesting study if you can find them, used ! )
If
you are purchasing more than one item please wait for your invoice so
that combined postage charge discount can be applied. Sending 1 or 4
items works out the postal cost.
