A database of the marks on a diversity of buildings is being created. In some cases it can be shown that individual masons worked on several buildings and so can, for example, allow dating of some for which no details are otherwise available.
It is proposed, some time later this year, to record the marks in Cambuskenneth Tower and The Kirk of the Holy Rude This will require 3 or 4 volunteers, all of whom will be trained. The data will be included in the Scottish Mason Marks project http://www.masonsmarkproject.org.uk/DisplayMarks.aspx
If you wish to volunteer, you can let us know directly by email; firstname.lastname@example.org
