Ship models: This was a standard size for ship models produced by Revell and Italeri but they have moved from it. 1:700: 0.435 mm: Ship models: This is the scale that most manufacturer chose to produce the largest series of waterline plastic model ships and submarines. Full hull models are popular in that scale as well. 1:600: 0.508 mm: Ship models
Models are built to scale, defined as the ratio of any linear dimension of the model to the equivalent dimension on the full-size subject (called the "prototype"), expressed either as a ratio with a colon (ex. 1:8 scale), or as a fraction with a slash (1/8 scale). This designates that 1 inch (or centimeter) on the model represents 8 such units ...
The reduced size affects the model's Reynolds number, which determines how the air reacts when flowing past the model, and compared to a full sized aircraft the size of control surfaces needed, the stability and the effectiveness of specific airfoil sections may differ considerably requiring changes to the design.
The product was named Otis King's Patent Calculator, and was manufactured and sold by Carbic Ltd. in London from about 1922 to about 1972.
