The Misko models are indeed superb, as are similarly the Amalgam Models range.
But to put it into perspective, they are produced by groups of highly skilled specialists in a small industrial envirinment, where various skills are pulled together to make the components for a finished model, and they both work in large scales as well.
Wingrove's models are to a much smaller scale and he did everyting from the initial research and drawings to making everyting himself in the early days, and later when he re married, his second wife Phyllis took an active part in the model making process. They have now retired to Spain.
There are other well known solo professional builders of model cars worth looking at who are on a par with Gerald Wingrove. Look at the models of Manuel Olive Sans, Rex Hays, Henri Baigent, Michele Conti, Guiseppe da Corte and Carlo Brianza who's models have become highly valuable over the years. More recently hobbyist and retired Kodak USA Engineer Tom Kirn has taken the Wingrove route and made some superb 1/15th scale models, and also Francisco Pulido in Spain. There is also a superb professional car modeller in the UK named David Hayward who works mainly in wood. All of whom are individual model makers.
If you have not heard of any of these artisans, a trawl on the internet should pull up some info and pictures of their work.
