Paul a couple of years ago. At the time I couldn't understand why he had parted with such an apparently useful model. Then I had a look in the box and all was clear. The parts are moulded - and not too well - in a type of plastic which somehow manages to be at once bendy and brittle. And for such a small model there are a lot of them. So back it went in the box., This process was repeated a couple of times over the ensuing years until I gave in and decided to actually build the thing.
By now you may be wondering if Paul and I are still on speaking terms. We are - and I unreservedly withdraw all the terrible things I said about him in the privacy of my toy room during the build.
Thanks again Paul - I have a plan to use this thing and I am beating it's attempts to thwart me!
