Font question-- "1984" movie

[primer]

Can anyone identify the font used for the INGSOC logo from 1984 (1984)?

Closest I could find is Geometric 231 Heavy or Kabel (but not the ITC version)

I think it's ITC Kabel Bold - maybe slightly compressed.

Thanks for the replies, with only 6 sample letters I'm not sure which of those is closer. I'll have to mock up the poster and try both.

The "G" on the ITC Kabel is completely wrong, but the other 2 fonts I suggested are close to identical from what I saw.
