Question Re G.b. KeVIII Coil Leader

Hello All,
I know I am delving into hens teeth material here but some questions about the 2½d KEVIII coil leader.

1. Does anyone on the list have one?.
2. Has anyone actually seen one?.
3. Does anyone have an illustration of one to show here?

Probably a couple of decades ago I had contact with a collector in the USA who actually had one in his collection which he subsequently sold. At that stage I did not think to ask him for details and now, of course, his e-mail address has vanished into the ether.

Can anyone confirm that the coil leader was similar to the other values issued for KEVIII.

Illustrations of the coil leaders on the other two values issued as coils can be found on our website.
If anyone is interested the direct link to the KEVIII pages is

or home url is

and click on the illustrated stamp booklet pane, which takes you to the section dealing with G.B. issues in the main.

Any help greatly appreciated.
Regards.
