Late model Rolls-Royce Merlin/Packard V-1650 Merlin details

[MIflyer]

Why is the Merlin used in the Canadian copy of the DC-4, the Canadair North Star, not listed? Those Merlin 620's had "transport heads" that were more durable than the wartime versions and are highly prized for restoration in warbirds.

One bit of data not yet mentioned are the production quantities for the Packard Merlin engines dash 11 and higher. I assume that each variant dash 11 and higher, the production was limited to a single digit number of engines for testing / prototype airplanes (and for some dash numbers, no hardware at all). But again, that is just an assumption... and we are all grown up enough to know what that means.

http://www.enginehistory.org/Piston/Packard/StatsAllPackardAero.pdf has the quantities built of most Packard engines.

For example, there were two V-1650-11s, two V-1650-17 and two V-1650-19s made, but the numbers for the V-1650-13, V-1650-15 and V-1650-21 were not known.
