Last time I was on exercise at Islay Airport (2001?), the tower was manned by a FISO and the firemen did everything else, so the change must have been a while ago.
The FISO on at the time was very helpful and a thoroughly nice chap. The firemen were tremendously hospitable, lending me their car for the afternoon and giving me a hearty supper of venison stew whilst I waited for the Herc to turn up after dark.
