Ik weet het niet maar de pdf die je krijgt door op onderstaande link te klikken geeft alvast uitleg over de maker van de beitel .
"Parallel to the development of Robert Sorby and Sons was that of a separate and totally
different company by the name of John Sorby and Sons which frst appears as registered in
the Wicker in 1797.
John Sorby was the brother of Thomas and hence uncle of Robert. He too was engaged in
the manufacture of edge tools, joiners tools, saws, sheep shears, fles and followed the family
tradition by being appointed Master Cutler in 1806. After his retirement his two sons, John
and Henry, continued the business and started to use the trade mark “I & H Sorby”. (At that
time there was no distinction between ‘J’ and ‘I’.)"

" The picture is further clouded with another edge tool manufacturer, C & J Turner, latterly
Joseph Turner and Co, using the “I. Sorby” trade mark which they acquired from Sorby and
Turner."
