Think you're more or less correct in suggesting the '30s to 'Courtneyneild'.. prior to that (so my old relatives used to tell us young ones), City were top dogs in Manchester, despite the odd relegation and just the one FA Cup win.
The Everton Cup final in 1933 was when City were firm favourites, only to get a chasing and a lose 0-3. The following year, we got back to Wembley expecting to be turned over by Pompey but ended up winning 2-1. Mercurial, or what?!
Then of course, as you say, who but us could finally win a first ever League title in 1937 and follow it up by getting relegated despite outscoring every other team in the league?!
Like every other Blue, I took City and indeed 'typical City' in with my Mother's milk. My first ever game at Maine Road In 1959 saw us put four past then champions Wolves.. only for them to put six past Bert Trautmann! I can still hear the Old Man complaining about 'bl**ding typical City' walking home up Lloyd Street..
And so on and so on it's been ever since. No matter what the ups or the downs have been, I've loved every minute of it and I do believe that along with all my fellow Blues who've all experienced the peaks and the troughs with our wonderful club, that we're all the better people for it as a result, more rounded in character.
Mind, having said that, just make sure we get the f-ing 3 points tomorrow at Wolves, lads..!!
