Gas Barbecue - in need of TLC (Booker HP12)

John Lewis Gas Barbecue with 4 burners, a cast iron griddle, top shelf and side burner hotplate. Glass window lid with thermometer. Cupboard below for gas cylinder and storage. Fat collection tub. 3 new burners supplied. Working order, used successfully for many years but we’ve moved to a different style barbecue. Will need a bit of a clean up and rust treatment but may be a refurbishment project for a club or charity etc. For collection in next 2-3 weeks or it will end up at the tip!
