1961 French GP Lap Times

I have a question on the 1961 French GP fastest lap time.

Looking at the ebook version of the Autocourse 1961-62, it show Phil Hill set the fastest lap at 2:27.1. Other sources have the same time and show it happened on lap 20. Looking at the lap time chart in Autocourse there are no times show that at less that 2:30. Does anyone have a source for lap times other than Autocourse or a different fastest lap time?

Mike Lang's "Grand Prix," Peter Higham's "International Motor Racing Guide," and David Hayhoe and David Holland's "Grand Prix Data Book" all credit Phil Hill with fastest lap in 2:27.1 secs.
However the September 1961 Motor Sport report of the race credits Moss with fastest lap in 2:30.4 secs on lap 2, which "DSJ" expresses surprise at.
On balance, 2:27.1 sounds the most plausible.
