Thanks for confirming about Spencer’s Pete. 
Did Tilcon have Routemans,dont remember seeing a pic of one ?
Wash your mouth out lad, we valued our ear drums! 
No, I worked for a BMC dealer and we serviced one owned by Sonning Haulage who had previously run Mastiffs. Because it was under warranty it had to have a new axle casing because it cracked slightly around the diff bowl. Reivers etc did the same and you usually saw them with oil streaks around the axle, most folk just welded them up but with it being under warranty it had to be changed.
