To be precise, there are two sites with the NMRS-name 'Gask' in Scotland:
1. Gask, Highland, NH63NE 3, NH 6675 3611, near Daviot & Dunlichity;
2. Gask, Aberdeenshire, NJ80NW 9, NJ 8018 0638, near Skene.
So my original posting was a valid one too.
No problem though, I will delete the Gask post so that you may go ahead with your Gask.
All the best!
Cheers,
Jan
