I have one in pieces, 8mm plate skin that needs a stud removed and replaced, lugs replaced and reassembled and the frame repaired. And a replacement lock... I got given a complete one ex a bank strip out and intend to use that in my build, so that one in pieces is now surplus... If you are interested let me know.
Edit: what was wrong with ultrathermic cutting? The lances are extremely good at what they do...
