Paxman has been involved in a wide range of engineering activities over the years and there are many strands to its history. The diversity of the material now available here - on more than 100 web pages - precludes the adoption any simple system of indexing in, say, chronological order or by technology.
Below I have attempted to order individual web pages within broad categories. Whether you are just browsing, or are searching for some specific information, a quick look at the category headings should give you a good idea of what material is available. Within each section you will find a summary of the content of each page in it and a link to the relevant page. Alternatively, you can search the site as explained in the next section.
At the foot of each web page you will find a link back to this page.

Also the order, customer, and application details of the approx 130 Paxman-Lentz steam engines built between 1907 and 1934, together with details of over 30 Lentz conversions carried out by Paxman on other makers' engines.
Listing of Paxman steam engines and boilers ordered between 1882 and 1910 for domestic installations, mainly to drive electric lighting plants in homes of the aristocracy and wealthy.
