The original control room clock from the 25 MW NPD reactor at Rolphton, ON. The overall panel size is 45 cm by 83 cm. The clock is a nominal 12” clock (glass face 27 cm). The second photograph shows the back of the panel. The third photograph shows NPD operator Julian Bayley in the control room in 1965. At that time the panel contained two clocks. The fourth photograph was taken in 1982 at which time the right–hand clock had been removed and the space was replaced by a blanking plate. The final photograph shows the original 1959 blueprint from the Self-Winding Clock Co. Inc. (Brooklyn N.Y.) dated 10 April 1959.
