Thanks for the comments, have a few more pieces from the same source just awaiting the inspiration as to how to avoid the worst of natures unwanted features. What has surprised me is how much this old timber moves after initial shaping, (it's known to have been in dry storage for 20+ yrs) it has to be worked inside and out in one session, even then there is no going back over previous areas, this movement has continued over the extended couple of days applying the oiled finish.
