This is the amalgamated data from three Mullard Data books from the late '20s to late 30's. I believe it covers all the valves Mullard made for domestic receivers between 1925 and 1937. Only those valves in current production, with full or half page data are listed. Valves still in production or stock for re-valving are not listed here. Much of it is not available elsewhere on the web as far as I know. The sources are:

Each file is an A4 sized PDF, suitable for printing.
