Companies distributing and selling consumer products have long known that the obsessive self association of fans with their chosen sports organizations can be exploited quite effectively in selling products. Around 1971 Tasco Sales licensed an NFL (US National Football League) licensing endorsement for their binoculars. The boxes were marked with the NFL logo and “approved” marking. The binoculars themselves were normal models without any special markings, so the consumer sports fans really didn’t get much that was special other than a pasteboard box. In fact the 12 x 40 # 505 ringsider model pictured above left and sold with the NFL endorsement were actually Tasco’s German and European model binoculars that were not really intended for the US market, complete with their German markings. But perhaps the sports fans thought “ VOLL VERGOTET” mean “Go Team”   and “WEITWINKEL” was meant “Quarterback Special?’ Actually, it is likely Tasco Sales saw it as a perfect opportunity to sell slow moving stock from one market in another market with that NFL endorsement and if the NFL saw the “VOLL VERGOTET” marking they just assumed the deal was fully coated in profits for them.

Even the most casual observer of binoculars will have noticed the wide variation in the overall length of binoculars. The design of binoculars always involves an interaction between prism arrangement and distance between lenses and lens diameter and the resulting magnification and width (angle) of view) and amount of light passed. With design aspects subject to practicality of use. The intuitive assumption is that longer is more powerful. Usually this is so, but not necessarily proportionally. Above left are Japanese WWII ship’s 15x80 binoculars(15x magnification) whose length illustrates the double telescope origins of binoculars and are of a size that is normally mounted and not hand held. Above right are Japanese post war 6x15 (6x magnification) binoculars designed to be small. If all other design factors are the same (they aren’t above) then a simple, inexpensive, and common way to increasing magnification is to increase the objective barrel length to allow an increase in the distance between the prisms and the objective (furthest) lens. The relationship of objective barrel length to magnification can be illustrated by the following examples, which are quite similar in design and in components except for the objective barrel length and objective lens diameter.

The United Falcon 20x40 (20 x magnification) binoculars have an extended   objective tube of around 125.7 mm  

By comparison United 10x20 (10x magnification) binoculars have an objective tube length of around 40 mm  

Dollands 8x20 (8x magnification) binoculars have an objective tube length of around 38 mm  

United 7x18 (7x magnification) binoculars have an objective tube length of around 25.5 mm  

Fata Morgana 6x12 (6x magnification) binoculars have an objective tube length of around xx mm

The components used in the Japanese reverse external poro prism miniature binoculars were suitable for use in compact spotting scopes, telescopes, and monoculars, and various scopes and monoculars appeared under a variety of brand names in various markets around the world at around the same time as the binoculars.
