Weber F/O seat, used on 727 and 737-200 thru 600.  THIS IS A GORGEOUS SEAT!!  Beautiful sheep, and belts.  Fully adjustable 8 ways, all internally so NO RAILS NEEDED.  Installs in 1 minute.  They do not move sideways the way the IPECO seats do, but for the first hundred years of aviation pilots just stepped over the corner of the seat and plopped their fat asses down.  These days our "cockpit managers" require the seat
to move out of the way to allow "easy access".  I digress...beautiful sheep covers, ops checked.  Once in place it looks identical to the captain's seat, no one will ever notice.
