Bentley BR2 WWI Rotary Aero Engine BOOK replica

Bentley BR2: World War 1 Rotary Aero Engine: Building the one quarter scale working replica by L.K. Blackmore.  Hardcover book published by Yalanga 1986, 95 pages with black and white photographs and illustrations.  This book contains a detailed account of the building of the one quarter full size working model of the famous Bentley B.R.2. aero engine which came into prominence in the closing stages of World War I. It represented a substantial improvement in both power output and reliability. It was the last of the rotary engines, in which the whole engine rotated around the crankshaft, which in turn was secured to the airframe.  The model of the B.R. 2. described in this book was the successful result of an attempt to restore the design of this historic engine. No drawings of the full size engine have been discovered, and very few examples of the full size engine exist. The original model, built by the Author, won a Gold Medal at the 1981 Model Engineer Exhibition at Wembley, and the Duke of Edinburgh Challenge Trophy at the 1982 Exhibition. Since then two other engines, built from the published drawings, have won Gold Medals at subsequent Exhibitions. Others are under construction. The great interest shown world wide in the Author's modelled to the decision to publish a detailed description of the building, which includes all the fully dimensioned drawings, with over fifty accompanying photographs.  The introduction deals with many interesting details about the full size engine and its development, and of course, its designer W.O. Bentley, who became better known for designing and producing the original Bentley sports car. These were contemporary with the other great sports and racing cars of the early 1930's.  The descriptive portion taken from the official Air Ministry Handbook has been reprinted in the Appendix, with the kind permission of the Ministry of Defence. This book itself is now extremely rare and was considered to be well worthwhile incorporating.  This book is in good condition.  The dust jacket is in fair condition.  It is currently protected by a removable plastic cover.  There is some minor wear to the edges (some creasing), corners and to the top and bottom of the spine (small rips and bump to the bottom, this has been repaired on the inside with sticky tape).  There is some minor shelf wear overall as well as some minor marks.  The cover is in good condition, there is some minor wear to the edges, corners and to the top and bottom of the spine.  There is crease to the front cover across the top right hand corner.  The book itself is in very good condition.  There are some minor marks to the outer edges.  The first title page has some creasing.  There is some yellowing of the pages.  Overall a good copy.
