Tried to reply to this earlier today, but it seems to have lost my post. Apologies in advance if it shows up later and this ends up a double post!
I'm not questioning Jim Taylor, the owner, but I think I can independently confirm that is CSX2171, not CSX2191.
I found reference
here to CSX2171, and photos at that site show what has to be this white slabside... right down to the matching Utah license plate.
But more importantly, my Dad owned CSX2191 from circa '67 or '68 through circa '73 (I don't know exactly the year he sold it, will have to ask him next time we talk). It started out as Guardsman Blue (which the AC Cars LTD Register of Cobra Chassis, as reprinted in "Cobra: The First 40 Years" agrees... CSX2191 - "bright blue black trim", and CSX2171 - "white red trim"). Later, CSX2191 was painted Maroon. But I can tell you it wasn't white, and in a barn, in 1971! I have photos of me as a toddler of a couple years old with that car... and I was born late '70. We've lost track of 2191 over the years, but I'd dearly love to know where it might be now (which is how I happened to stumble on this particular forum posting!). If anyone actually does hear of a lead on 2191 I'd love it if you let me know.
The 427's are unquestionably bad-ass, but the Mark I and Mark II Ace-chassis 289's have a special place in my heart.

p.s. I gather, from reading some other posts on Club Cobra, that quite often the history of specific serial #'s are sometimes kept quite "close to the vest"... not really sure I understand why... but apologies if I've offended anyone by sharing my personal history with CSX2191.
