Fairgrieve

What little information exists can be found in Jeannie Campbell's Highland Bagpipe Makers.  She found a Walter Fairgrieve born in Edinburgh in 1874 that was a wood turner, however no business in that name.  Jeannie surmises that he might have worked for one of the Edinburgh bagpipe makers and did some work on-the-side, perhaps with every intention of establishing his own business.  The pictures here are courtesy of Andreas Hartmann-Virnich.

I highly recommend Jeannie's book.  It is remarkable.
