PictureSheffield has a 1970s photo of the entrance to Cobnar Works, when it was occupied by engineers
It also has 2 adverts from earlier when the sickle manufacturers were the occupiers.
The Directories file onthis site, over to the left, has the Linacre occupiers in both 1925 and 1905

Thank you. I had seen the ad's before but not the 70's picture.

Geoffrey Tweedale's Directory of Sheffield Tool Manufacturers has an extensive entry on Linley, Linacre and Bingham, including no fewer than 9 reproductions of adverts (his directories do not include photos of buildings).
