aghh the old 47 . mine was G-BHKW with the turbocharger . Great machine for spraying but now i think in Cyprus... Anyway cheque for £250 on the way and good luck. As for any ( unlikely) left over , i dont think it makes sense to try to send back pro rata ..what aheadache
May i suggest that it is either sent to a charity ( helpforheroes??) or kept for the next poor soul that comes up against injustice from the caa ?? Just a thought.
