Canon 65mm MPE Lens for sale

This is one of my own lenses which I bought this a few years ago thinking it might be useful for macro work but I've since bought a 60 Macro-Elmarit-R and converted it for Canon so one is irrelevant as both will now do the same job - I prefer the Elmarit with extenders so the Canon is now up for sale. The MPE is near mint and boxed - I have an Arca QR compatible adapter for it which I will throw in. £600 in the UK/EU inc vat or £500 outside the EU (no vat for export or within the EU to a vat registered business after supply and check of EU vat number. Thanks.
