What does a LWB shell look like? I have an old Meteor that I'm restoring for a cousin that came with a lexan shell. It doesn't look like that one above - it's got side pods that stick out to accommodate the transverse stick pack. If that's LWB then I dread to think how short the SWB is!
The bad news is that it's quite poorly cut, with jagged edges everywhere, and it has been painted on the outside...
Not sure if it could be used to make a mould from, but I'm willing to let Keith try if I get a good deal on some replacements!
