Certainly a contender with heavy Wright investment. Suppose it was easy to pencil in the E400 at 75** and the VDLs at 76**. 
With the ex-Yorkshire Tempos, their Yorkshire numbering (1300-1312) sort of fit in to the NE system... before the Belmont Darts. Even with the addition of the Tiger ones if that ever to happen.
