Terence, your new camera or one extremely like it is shown in the 1954 British Journal Photography Almanac. The Kodak advert shows a half plate Kodak Specialist Camera Model 2, but all the hardware etc is the same as your whole plate. By 1961 the Specialist Model 3 is all metal.

I may have an older BJP Almanac with an advert for your camera in the UK, I will scan it for you if I find one.
