This volume is contains transcribed/copied records of naval estimates from August 1673 (shortly following the removal of the Duke of York as Lord High Admiral) through to the end of 1689. It is absolutely critical for anybody who is studying the Royal Navy’s finances during this period, at least from the perspective of planning, if not really reality. These estimates cover everything from wages to the material costs for building warships, and provide an intense level of detail.
as you can see here, the lengths of these estimates can vary greatly, with some taking up only a portion of a page and others taking up several pages- especially those that have to do with the construction or maintenance of several warships.
Quite frankly, this volume would be prime for creating a database, although the designer would have to do quite a bit of work to ensure that each report structure (or sub structure) could be accurately represented in the database.
I have 123 images from this volume, and they are remarkably clear and useful to anybody interested in this volume.
