There are a few british NOS on ebay but I was wondering and its a long shot if anyone has or knows where to acquire a Sears Silvertone Valve of the same spec? Just for authenticity purposes
Cheers

Per the picture you posted, the radio has a valve that has been replaced by a substitute valve, the convertor or frequency changer. The socket has been rewired for a 12SA7, which is a metal, single ended valve, an electrical equivalent 12A8GT, that was originally supplied. The 12SA7 is a US Army surplus issue probably RCA sourced.
