AR-15 Comanche Operation and Maintenance Manual

I came across this Colt AR-15 Comanche manual on Facebook about 15 March 2019. I know zero about the Comanche. I pointed a member of the group to the Comanche manual because I thought it was a key piece he sought for his early AR collection. I messaged the seller (has sold firearm books and manuals for almost 50 years) to see if he had any background info on the manual. He said it is the only Comanche manual that he has ever seen. The buyer is going to provide me a few better pictures in the future.
