I find it peculiar that Wilson owned a Voxola PR-76; Considering that before the factory of the same name burned, few had been distributed.
Also, even more curiously, both Wilson and Wagstaff are currently the only two characters who have shown us to have been able to build a working gate for the Constant, apparently with "trivial" Earth technology.
What if Wilson knew about Wagstaff? He was an undisputed genius; in the game he invented teleportation, an android with free will and he is in possession of an occult technology that makes him capable of projecting his own ghost "avatar" without having to travel with his physical body.
In short, surely Wilson would have been fascinated by such a genius; perhaps as a young man he decided to follow Wagstaff's footsteps, and for this (not by chance) he took possession of one of the few Voxola PR-76s in circulation.
Ponder people, ponder.
