anyone know how many 1971 Twisters were produced?

Very interesting gunmetal72. Did you sell it here in Calgary? Man, wouldn't that be one to find again. Say, did you have a Kevin over your way this past weekend? Speaking of gunmetal grey (or in Canada, Winchester grey), one of '71 Swinger 340 Specials in A4 was/is here in Calgary someplace, last we heard it was sold to someone in McKenzie Lake.
