Livery will often have elements of the heraldry relating to the individual or .... Such models are sometimes frowned upon in the model-building community because they do not represent existing items, but are original designs. Because they require no licensing fees for trademark and design owners, and can thus be produced less expensively, freelance models are quite popular in the United States. They have not become popular in Europe, although a few European companies produce them.

E452
Polyphosphates are salts or esters of polymeric oxyanions formed from tetrahedral PO4 ( phosphate) structural units linked together by sharing oxygen atoms. Polyphosphates can adopt linear or a cyclic ring structures. In biology, the polyphosphate esters ADP and ATP are involved in energy storage. A variety of polyphosphates find application in mineral sequestration in municipal waters, generally being present at 1 to 5 ppm. GTP, CTP, and UTP are also nucleotides important in the protein synthesis, lipid synthesis, and carbohydrate metabolism, respectively. Polyphosphates are also used as food additives, marked E452.

Model Building
Model building is a hobby and career that involves the creation of physical models either from kits or from materials and components acquired by the builder. The kits contain several pieces that need to be assembled in order to make a final model. Most model-building categories have a range of common scales that make them manageable for the average person both to complete and display. A model is generally considered physical representations of an object and maintains accurate relationships between all of its aspects. The model building kits can be classified according to skill levels that represent the degree of difficulty for the hobbyist. These include skill level 1 with snap-together pieces that do not require glue or paint; skill level 2, which requires glue and paint; and, skill level 3 kits that include smaller and more detailed parts. Advanced skill levels 4 and 5 kits ship with components that have extra-fine details. Particularly, level 5 requires expert-level skills. ...

Livery
A livery is an identifying design, such as a uniform, ornament, symbol or insignia that designates ownership or affiliation, often found on an individual or vehicle. Livery will often have elements of the heraldry relating to the individual or corporate body feature in the livery. Alternatively, some kind of a personal emblem or badge, or a distinctive colour, is featured. The word itself derives from the French ''livrée'', meaning ''dispensed, handed over''. Most often it would indicate that the wearer of the livery was a servant, dependant, follower or friend of the owner of the livery, or, in the case of objects, that the object belonged to them. In the late medieval phenomenon of bastard feudalism, livery badges worn by the "retainers" of great lords, sometimes in effect private armies, became a great political concern in England. Etymology "In the ''Black'' Book of 1483, it was laid down that each person should receive "... for his Livery at night, half a chet loaf, o ...
