mounter

The great foes of Turner, as of all other great colorists especially, are the picture cleaner and the mounter.

While gazing at the lofty tower of the Cathedral, I was accosted by a cicerone: 'Voulez vous mounter?'

As, however, it was only a “mounter,” it was thought best to keep the hawk for the chance of a ringer later on.

Drury Lane isnt in it with us, though what the blazes you are doing as a Mounter beats me.

Higgins' photo mounter and other like bottled pastes are better.
