I recall visiting the PB when I inspected the car 2 years ago. I hope all is well with it?
I have a Carcoon-type positive air pressure enclosure which I bought s/h for my PA but am very unlikely to use. I will check to ensure that it is working order
£50 should secure it - plus postage, or buyer can collect!
I got an outdoor cover from Hamilton Classic, ( I have no connections ) for my J2, it cost a bit more than the one offered earlier. For your info I sent the dimention's of the J2, and they suggested that a cover which fits a Lotus/Caterham 7 is about right. Having got it, it is a little large however I have never put it on with the hood up. I use the outdoor cover in the garage and when touring. I hope that this will help.
