As I stated in my email there was never any references of the current abbreviations use given when it was implemented and it has been a mistake from the beginning. As David says "I don't think its the responsibility of tz to report what tz did in the past - but to represent what was in common use in the past."

"To be clear, the TZ Coordinator SHALL NOT set time zone policy for a region but use judgment and whatever available sources exist to assess what the average person on street would think the time actually is, or in case of historical corrections, was."

This is not applicable. "the average person on street would think the
time actually is" - /time/ not /abbreviation/

And it is common practice that the maintainer invents new abbreviations.

Did you look at inventend abbreviations as suggested at
http://mm.icann.org/pipermail/tz/2013-April/019001.html ?

So, here some lines from the Europe file:
I invented the abbreviations marked `*' in the following table;
# the rest are from earlier versions of this file, or from other sources.
#       -3:00       WGT WGST      Western Greenland*
#       -1:00       EGT EGST      Eastern Greenland*
#        0:19:32.13 AMT NST       Amsterdam, Netherlands Summer (1835-1937)*
#        0:20       NET NEST      Netherlands (1937-1940)*
#        1:00:14    SET           Swedish (1879-1899)*
