Ghost sign

Yet another previously unnoticed ghost sign. It is difficult to see but you can see it sandwiched on the horizontal stone in between the "poundsaver" and the flags.

I think it reads "John Mc (something) and co".

I had a visit to RCAHMS today to see the plans for the Flannan Lighthouse for my talk. It was very cool to see the original plans, drawn by David Alan Stevenson and was a very useful trip.
