Vintage A. G. Thornton Engineering Slide Ruler in Case

This item was donated used and thus will show some signs of wear from age and use, but is overall in good condition.

The case has "WEC" cut into it, then written in pencil underneath, and finally etched onto the back of the ruler. We assume these are the initials of the previous owner.

PLEASE NOTE: The glass slider part of the ruler has a crack in it

Ruler is 30cm long. The removable middle section is 31cm.

Please see photos for best idea on condition.
