As stated in the disclaimer on the Home Page existing Tangye records are rather sparse and confusing for early engine production, the majority of these pages have been obtained from a variety of sources such as catalogues, the register, some saved documents and a lot of research by others over many years that we are now able to piece some of the Tangye story together.

Using the above but mainly catalogues I have develped the table below to show engine development for early Tangyes

As additional data is obtained the details on this page will be updated.
