King,
Just a note...In the auction you mention you've never seen one with papers before...I have a near twin but it's Glacier Blue..
Has a thread here about a year ago when featured in Hemmings Muscle Machines....
Has all it's papers..POP..Blue cloth too!
Completely 'born with' numbered parts and sheetmetal/paint...
'Born with' numbers matching cars L-78's do exsist...
Good luck with the sale! Should be worth all what you want for it!
