Thanks Shackman, clearly when is say IIRC, it is nowhere near C! My defence is that I left the 350 line for the 412 line in 2006, the exited FBH altogether in 2007, never looking back!
That pic is brilliant, brings backs memories of early one morning, me signing all the PDC's off for the day, when one of the mech's walks in white faced from the shock he gave himself hitting the float button and hearing a rather loud bang! Followed by a rather tricky situation to get out of the cab and back to the line!!
