Blundell Harling LTD. Radiac Calculator No.1 Mk. 2 Circular Slide Rule
is an uncommon Blundell Harling LTD. Radiac Calculator No.1 Mk. 2 Circular slide rule. Made in Weymouth, England. The slide rule measures the time from a nuclear burst. It works for either sea or land. (The two top wheels can be removed and flipped to switch between surfaces as desired.) The instructions are printed on the reverse side of the slide rule.
It is made of plastic and has a diameter of approximately 5 inches. It is in excellent condition and doesn't look like it was used very much (if at all). It comes with the original case, which is in very good condition. Both the slide rule and the case are free from any names or added markings. (Please take a look at the links to scans below, showing both the land side and the sea side.)
