I don't think I have ever seen a DC-3 being rope swung but I did witness (on two occasions) a C-46 at Salalah successfully having an engine started using a piece of sacking, a long rope and six locals exiting stage right as fast as they could go.
If I remember correctly the C-46 had R2800s so they were a tad larger than the R1830s in the DC-3.
