I've got an apple tree, variety "Spartan" trained as an espalier that is
now
in blossom. I've also got a Crab Apple also in blossom. Will this be
enough for pollination or should I help with a small paint brush.

Hi,
I'd tend to play safe with the paint brush - unless you have a lot of
pollinating insects on the go at the moment - bumble bees and the like.
