Thanks Jack
... you have confirmed all I have found... like you it was notably missing from Tweedale but not sure every little known cutler from Sheffield is included in that book - though Tweedale is a great resource with many listings... a friend of mine like you noted there were John Butlers he found in old directories from Sheffield but not a John "Hart" Butler... interesting and I suppose a more rare maker to find... Your input is so much appreciated Jack!!!
