The M8136 box plate Mullard is a good tube if an early 1960's version - the very common 1970's version is a pretty dull affair, rumored to be made in China and assembled in the UK - and fakes abound.

1ED5 is a date code, not a tube designation. Brimar m,ade many variations of the 12AU7, again, later ones were imported and not made in the UK. Mullard never made a 5963, if one is so labelled, it is likely an RCA or GE, again - eraly ones are vastly better.
