Ok, I cant resist I was perving the 1978 catalog Hogsy posted....no yellows.....no limes..... looking at this lid vent (raised logo)..... I wonder.... Did the lid vent go to this style in 1977? Was the engraved vent only used for 1 year? Its got me questioning my brown 22 now too... Not that it really matters in the grand scheme of things, but it helps to determine a year.
If your rolling your eyes at me, it's ok.. I'm a nerd wanting to determinine the model year.
Oh and +5 on showing it all hot and ready!
