The Museum Catalogue is a large PDF file that lists everything held by the museum as of January 2024. It can be downloaded by clicking on the PDF icon. It is about 190 pages long so I would suggest using search to find the items you are interested in rather than printing it out. Just click on the magnifying glass and type in whatever you are looking for. The relevant items are highlighted and you click through them to see all the relevant entries.
However please be aware that Purton Museum does not have the resource or equipment to copy documents from the collection, however, you are welcome to view anything of interest by making an appointment with the archivist. Contact details are in the 'Contact Us' section. Please give at least a week's notice.
