Is that an Otis King?


No it is a plastic one that has a plastic insert that also has all sorts of useful Chemistry, Physic and SI/Imperial/US unit interconversion information.
It was a trade gift from BOC to my Dad that I acquired in 1962.   In fact it must be 50 years old last year not 48!!  It is now antique.

Jan and I both used to have the good old Otis for our calcs back at UKAEA in the 60's. I bought the wife one off ebay a year or so back as a small momento. Still managed to remember how to use it after 40 years absence.
