You can tell the Model 70 apart from the Model G because it has vertical grill louvers instead of horizontal. At a distance it is hard to judge it's size, but you can tell that it is not a Model 50 or Model 60 because it has a "bulged frame" to accommodate a larger engine. (Those front tires are larger than the "stock" size, by the way.)
The 70 was available in the "rowcrop" front wheel configurations (shown here as a dual-wheel tricycle), the "Standard" front end, and also as a "Hi-Crop". The 70 was also available in all of these versions with a diesel engine and an LP gas engine.
