Bit late in the day here as I have only just registered on this site. But you may be interested in the Barmaster's maps I uploaded to AN some time ago. These were the ones: 1760s map of Hillcarr Sough; (not Barmaster's map) : Alport area, Ball Eye area, Bonsall Moor North west, Bonsall Moor North, Bonsall Moor South, Bradwell East, Brushfield, Carsington Pastures, Cromford East, Dene Hollow area, Elton area, Hopton Cross Roads area, Hopton, Lathkilldale, Masson Hill, Matlock East, Ryder Point area, Six inch Bradwell, Six inch Peak Forest,Snitterton area, Stanton in the Peak area, Wensley, Winster area, Wirksworth town, Yokecliffe Rake, and Statham's 17C map of the Dove Gang mines. These, together with Symond's 1850 map of Camborne and Illogan. Jim Rieuwerts asked me to copy them and I gave him large photo prints of the results. There were copied onto whole plate cut film using the equipment of my long lost previous employer and (from memory) T.D.Ford requested I turn the latter over to him ! Not happy about this so I sent him a batch of quasi sub standard copies! If you wish to get in touch with me I would let you have copies but they would have to go on to my One Drive, or similar since each file is 11.6 Mb! They were especially copied to retain the Barmaster's pencilled annotations. Just learned the AN is likely to be defunct which is a crying shame.
