Full set by J M & H Cronmire, 10 Bromehead Street, Commercial Road East, London in an eight inch rosewood veneered case. Their trade label was affixed to the underneath of the instrument tray and the ivory protractor, above, is also signed. They were at this address from 1865-69.
When I obtained this set the instruments were not located in the correct pockets and it has been a puzzle to work out their correct locations. I had not realised that in sets from the middle of the nineteenth century the spring bows did not necessarily have separate pockets but were sometimes arranged in a line in one large pocket as I have now arranged them. I posed the question of how they should be arranged to members of the Yahoo drawing instruments group (link on Links & Contacts page). Robert Pilla posted a picture of his Archbutt set of about the same date showing that the spring bows were arranged in this way.
The instrument in the uppermost pocket is a road pen. It will be noted that there is one instrument missing. This would have been a six inch plain divider.
I have shown the spring bows separately as they rather unusually have ivory handles.
