Is there more than one symbol for the tenor clef?

[Northern Piper]

I've been going over some music theory and want to memorise the Great Staff for the sound compass of the Highland pipes. I want to put the tenor clef in for the A one octave below middle C (i.e. - the A one octave below the A below middle C). One source that I've got uses a symblol that looks like a big "K" for the tenor clef, but another source uses a sort of stylised "B" - like this (http://www.music.vt.edu/musicdictionary/textt/Tenorclef.html).

Are these just two different but equivalent symbols, or is there a difference between the two symbols for tenor clef?

Thanks.
