Published in 2004, this high-quality large-format softcover book entitled "České Modelářské Motory" (Czech Model Engines) was compiled by Jiří Linka and Jan Kafka. In essence, it is a photographic record of the remarkable collection of Czech model engines assembled over the years by Jiří Linka.
The book contains relatively little historical detail relating to the illustrated engines, confining itself to the date of introduction plus some basic physical data. It does however present multiple views of the illustrated engines taken from different angles. Accordingly, it is an invaluable resource for identifying and dating a particular model which may be in the reader's possession.
I assume that the book is no longer in print. However, I imagine that copies may appear from time to time on offer through eBay and elsewhere. Anyone interested in the remarkably prolific history of model engine production in Czechoslovakia (as Czechia was formerly known) will find this book to be an indispensable reference.
