I'm going to apologise to Captain Blood, I have read the post now from the Perry's Facebook page, where they also use the term "obscure". I thought that was you being self-righteous, when you were just repeating the post. So, apologies.
As someone with an interest in Brazilian conflicts (due to my partner being Brazilian), I am looking forward to this range (and the Hooker’s/Foundry is a lovely book on the subject).
