I remember it at STN as N reg and a single standard CL-44 with Swiss reg and a visitor CL-44 called River Plate airlines. They were all grand a/c as I recall one that appeared derelict close to TMAC engineering which rebuilt it and it took off some months later, a carpenter having built a craddle for it to be craned onto. Some very nice girls worked in the TMAC offices both sides of STN airport.
