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.
