Getting vehicle from spawn brick

[[USSR] Diggy]

If all I have is the spawn-brick %brick to work with, is it possible to find the vehicle or vehicle type that is spawned from it? I've done a search through the forums but couldn't find anything about this.

%brick.vehicle
%brick.vehicleDatablock

On the converse:
%vehicle.spawnBrick is the brick that spawned the vehicle
%brick.vehicle.spawnBrick is the same as %brick
All is easily found with /getid and dump()
