Delivered new to Eastern Air Lines in Mar-67 as N8158G, the aircraft was fitted with a main-deck cargo door and could be used in either passenger or freighter configuration, it was sold to FedEx Federal Express in Jul-81 and re-registered N122FE in Nov-81. It operated with FedEx until Feb-94 when it was sold to Kelowna Flightcraft Charter, Canada, as C-GKFB. Kelowna Flightcraft operated it on behalf of Purolator Courier until it was sold in Jun-01 to Angolan cargo operator, Air Gemini, and registered in Sao Tome as S9-BAU (it was originally to have been S9-IAO but the registration wasn't taken up). S9-BAU was re-registered in Angola in late 2008 as D2-ERN (photographic evidence from Nov-08) and as far as I can tell from the information available, it was still in service in early 2015
