ISTR the Puma had a pitch gauge that stopped at 15 degrees.
Eh? I've not flown a Puma since 1994 and so I might be wrong, but I think the collective pitch gauges in the ones I flew in the RAF for three and a half tours indicated up to 18.5 degrees. I'm fairly sure the CP limit for take-off was 15.5 degrees, then backed off to 14.25 for the climb.
