Hi Rod! This is 8 years old thread, from 2011. Back in the time, I think that I have sold that revenue to a collector known as "Revenue Reverend"... I think that it has been unique one known with a reversed surcharge.
You can see a reference on his page:
https://www.revrevd.com/seychelles.htmlWill be nice that I can get it back, but will be even nicer to get the last 8 years back...

And Rod, please, feel free to send me an email anytime when you will see that I am not replying... just don't see all messages, and I don't like to miss to reply when someone is asking something!
