You're right of course, the EM84 was the tube with the double ended single bar style display, it's rather funny in that the EM85, which I would have guessed came out later due to the number, uses a similar fan display to an EM80, but it has a dual action to the fan. The European (actually Phillips) numbering standard always mixes me up, it's also confusing because they numbered tubes using that standard that have no connection to Phillips at all, such as the war time German metal tubes that look like an over sized 6H6.
