When I started flying them in 1980, all of ours were ex-C47s used as freighters and all had MGTO, MZF and MGL at 26,900 and V1, Vr and V2 at 84.2. If you could explain where the .2 knots came from, the oral was over.
It's not flat rated but de-rated from 1424 to about 1220. It'll pull that till 30 degrees C.
