Usually Mullard tubes will have a hole in the bottom of the guide pin and small letters/numbers etched in the glass near the base.The "[two letters]" are "GR" for Great in Great Britain. Most of the time when the tube is relatively small in size and has the European GZ34 designation and has GR Britain on it it is either a Mullard or a fake. I doubt someone would fake a Westinghouse Brand.
