Hi Vandoo.  1912.  There is some of the material collected in the Natural History museum London.  I have found that this is a collection of skulls, I thought that sort of thing had stopped by then.  I would imagine that some of the insects may be there also.  There may be some material at the FitzWilliam Cambridge where Wollaston was a tutor, only to be shot by a pupil who then took thier own life.
