The carpenters marks I have described are assembly marks, and will be found in pairs either side of a joint. If other marks are identified they should always be recorded so that analysis may be made of them.
Two types that relate to the setting out construction of a building are 'two foot marks' and 'levelling marks'. Laurie Smith is collecting other forms of unidentified marks to see if they form a plan of the building and would welcome any examples.
Non-construction marks include evil averting marks, the most easily identified of which are the overlapping VV that looks like a W and the daisywheel (See write-up of the 1997 Annual Lecture in the Jan 1998 DBRG NEWS).
Finally the mark to the left occurs in many places on timbers at Wyndrums in Ewhurst, but apparently not more than once on each frame. It is definitely not an assembly mark as it is away from ioints and is not always on the upper face. Could it have been to identify the frames of the house at a frame yard where more than one frame?
Remember your thoughts on carpenters’ marks would be welcome to feed into further research.
