1970's Collins INS 61-B Inertial Navigation System Guide for Pilots

Description

This is a Pilot's Guide to the Collins 61-B INS system.  It has staining on one edge but it goes away the deeper you get into the manual pages.  37 pages and a small "cheat" card. Ships flat via Media Mail.
Thanks for looking.
I usually ship the same day an item is paid for.
On occasion it may take the specified time if I am on a work trip.
I will advise if this is the case or it will show that “seller is away” at the top of the ad.
Please pay within 4 days.  Item will be subject to an eBay unpaid item claim and/or being relisted after that time.
