The Curtiss OX-5

The Curtiss OX-5
by Kimble D. McCutcheon

The Curtiss OX-5 has the distinction of being the first mass-produced aircraft engine in the United States. First available in 1915, it served in trainers through World War I, continued to be produced by Curtiss as well as other licensees until 1918 or 1919, and then powered a veritable explosion in general aviation after the end of the war and for a decade to follow.

Help Needed:
Bristol Centaurus

An Australian group is overhauling a Type 18 Bristol Centaurus engine. The intention is to return this engine back to Airworthiness, and then be reinstalled back into the Sea Fury that is also being overhauled to Airworthy standard.

Whilst we do have some parts and information for this job, we would like to know more! If anyone has information, or knows of someone that may be familiar with the machining process involved in the manufacture of the sleeves, and even the machines used for this job, it would be greatly received and very much appreciated.

We do have some information (metallurgy content , tolerances) but we would like some of the finer details of the machining process, and the machines they were produced on. If anyone has this information, please pass it on via

Thank you.

Rolls-Royce Merlin Book

The Rolls-Royce Heritage Trust is putting together a book about the Merlin engine. We would like to include a list of surviving engines, and to this end any help would be appreciated.

All that is required is the mark and serial number of the engine, be it airworthy, on display, in a museum aircraft or in private ownership. Engines must be complete or substantially complete - no wrecks. All marks are eligible for engines made in the UK, USA and Australia, the exception being the Mustang Packard V-1650s, which are too numerous (but we would like to include those built by Continental). Any such knowledge about Merlins other than those in USA/Canada would also be helpful.

If anyone would like to provide me with such details they can e-mail me through
