7 Blade Fan

[427.060]

I have a 7 blade fan and clutch that I need decoded. It has 3931002 and 913894.H68 stamped on the blades. I don't know if the clutch is original. I don't see a manufacturer name on it. It has THERMATIC FAN DRIVE PATENTED-PANTENED CNANDA 1961 OTHER PATENTS PENDING On the front. What is this fan and clutch correct for?
Thanks, James

That fan was originally used on 1968 396-427cid Impala-Belair-Biscayne-Caprice w/AC or HD cooling.The shared clutch for that was dabbed brown-tan & #3931004.
Does the clutch you have,have a coil spring or is the bi-metal strip? Do you see a number or date on the waterpump mating area & ridge?

Thank you. It's not a coil spring clutch.
