Yes - for example, back in 1992, the "Europe" file had these zones:

$ git show a544b29c474e03e527df186cd9c33049bce31670:europe | egrep '^Zone'
Zone	GB-Eire		0:00	GB-Eire		%s	1968 Oct 27 1:00s
Zone	WET		0:00	W-Eur		WET%s
Zone	Iceland		0:00	-		WET
Zone	Portugal	0:00	W-Eur		WET%s	1992 Sep 27 1:00s
Zone	MET		1:00	M-Eur		MET%s
Zone	Poland		1:00	W-Eur		MET%s
Zone	EET		2:00	E-Eur		EET%s
Zone	Turkey		3:00	Turkey		EET%s
Zone	W-SU		3:00	M-Eur		????

(Paul, I think, constructed the tz Git repository, in part, from the original SCCS history from when SCCS was being used by Arthur).
