Identify both airlines, the two aircraft specific to variant and the route to be flown.

I have to believe that the connection point was in Africa rather than Europe; that said, any service from Europe to sub-Saharan destinations in the interior would have almost certainly been on UTA from Paris/CDG, which would seem to leave African points along the coast -- east to west: Lagos/LOS, Accra/ACC, Abidjan/ABJ, Monrovia/ROB, Conakry/CKY, and Dakar/DKR. A narrow-body from ZRH would have been a Swissair DC-8-60

LOS is most likely out because Nigeria Airways was a 707 operator, I don't like ACC for the distance from FNA, and I think both DKR and ROB saw enough traffic to warrant wide-body flights ... so my first guess is a connection at ABJ to UTA

An excellent and well thought out guess, but no - unfortunately you're a bit off here. Swissair was indeed the first carrier out of Zurich, but the aircraft was not a DC-8 of any variant. Neither UTA nor ABJ are involved in this routing. That said, knowing what you now know should prove to be most instructive. Good luck with your next guess!
