It's not very clear from these photos was was actually left of this thing when it was first acquired. It looks like there was nothing more than a metal frame and no interior or shell. Are there any good photos documenting what actually existed before the new pieces started getting fabricated? Post-restoration you're going to want to know what's still original and what's not. If there's nothing left of the shell after restoration, it's really not much of a restoration anymore. It's a recreation over a metal framework that could just as well have been built from scratch also.
