Thanks for your reply. Pictures going in the post today. I hope you like them.
Yes I would really like to see a copy of the Avern letter. It's all grist to the mill. I really have to scratch around to get any English corkcutting material.
Yes I do know about Palafrugal. The museum there were very helpful at the beginning of my research. They are having a "cork conference" there in February next year and I am working on a paper about English corkcutting to present there then - hence my finding this message board for Avern.
I will let you know anything more I find about the Averns as it crops up.
