Compass Lynx 304/2 gas locker lid needed

I have a Compass Lynx 304/2, made in 1998. The gas locker lid flew off on a motorway and could not be found. I've not succeeded in finding a replacement. I wonder whether any club member with the same van would be willing to lend me their gas locker lid for a short while so that I can get a copy made by a specialist manufacturer or 3-d printing service.
