Following the patent and release of Harold's Long Scale calculator featuring two knobs on the outside rim in 1914, he designed the Magnum Long Scale calculator in 1927. [6] [7] As the name "Magnum" implies, it was a fairly large device at 4.5 inches in diameter—about 1.5 inches more than Fowler's average non-Magnum-series calculators. [8]
The calculator was sold in a hinged mahogany case 46 by 12 by 11 centimetres (18.1 in × 4.7 in × 4.3 in) which, if required, holds the instrument when in use by means a brass support that can be latched to the outer end of the case. [6] [7] Out of its case the calculator weighs about 900 grams (32 oz). [8]

Models which are commonly made in scale at 1:150 are commercial airliners - such as the Airbus A320, Boeing 777 all the way to the jumbo jets - the Airbus A380 & Boeing 747. [8] 1:148: 2.059 mm: Model railways (British N) British N model railroad scale. 1:144: 1 ⁄ 12 in: 2.117 mm HOO scale - Popular for ships, aircraft, rockets, spacecraft.
Thus the scale and approximate prototype gauge are represented, with the model gauge used (9 mm for H0e gauge; 6.5 mm for H0f gauge) being implied. [ 2 ] The scales used include the general European modelling range of Z, N, TT, H0, 0 and also the large model engineering gauges of I to X, including 3 + 1 ⁄ 2 , 5, 7 + 1 ⁄ 4 and 10 + 1 ⁄ 4 ...
Narrow-gauge models in this gauge can be as large as 1:3 scale. 5-inch Live steam: 1:12: 127 mm or 121 mm Ridable, outdoor gauge. The gauge is 5 in (127 mm) in Europe, but 4 + 3 ⁄ 4 in (121 mm) in US and Canada. For standard gauge prototypes at 5 inch, the correct scale is 1 1 ⁄ 16 inch per foot or approximately 1:11.3. Alternatively 1.1/8 ...

The next largest scale range, G scale (1:22.5) in the US and 16 mm scale (1:19.05) in the UK, and as large as 1:12 scale, is too small for riding but is used for outdoor garden railways, which allow use of natural landscaping. G scale is also sometimes used indoors, with the track mounted adjacent to walls at eye level of standing adults.
