P38 exhaust finisher

hi, i have just put a new exhaust system on my p38 1996 , its a britpart system with single rear pipe. i have seen parts books showing my system with a chrome finisher that bolts to the rear pipe.
the part number is ESR 3153 yet i cant get one anywhere.and even my local dealer knows nothing about one.
am i cracking up or did this part actualy exsist or not.

ebay ?

thanks ive looked at them but they dont look like they will fit as the exhaust is actualy oval ish and i was looking for the one that was made for the actual exhaust.not an after market all rounder.

genuine LR around £45 incl. VAT from Rimmer Bros (In stock).

thanks for that will order now
