An invaluable source of information on a wide variety of model engines that many readers have probably already come across is José Manuel Rojo's fascinating and very useful website which presents the world-class JM Rojo model engine collection for interested readers. Although presented in Spanish, it’s easily translated into any language using Google Translate or some similar program.
The site includes an imressive assemblage of excellent images of model engines from around the world, including a number of very rare and exceptionally interesting models. These images are accompanied by some very useful descriptive material. Reference to contemporary magazine articles proves beyond question that several of José Manuel's cited dates as well as a few details of the engines themselves are in error, but this in no way detracts from the interest and value of the site.
The site is very well organized. making it easy for the reader to navigate through its wide-ranging content to zoom in on an engine of particular interest. I use it myself on a regular basis while preparing my own articles which appear on my own site. With José Manuel's kind permission, I’ve used a number of his website images in those articles, with my open and grateful acknowledgement.
Overall, this is a highly recommended resource. By all means take a look!!
