*Iron nails at this time would have been hand made by the blacksmith and each one slightly different.
The nails would only be only be used to 'fix' a brace to the arcade post and would be a long term measure. The notches with nails remaining today are the result of the braces being recently removed.
The blank shoring notches (i.e. without nails or nail holes) housed temporary props whilst the post base was being shortened.
