On the off chance that this chassis still exists, and if the owner is a forum member, I just been digging through some books I've collected and found the warranty and service voucher record for this chassis. The book is in as new condition has all the vouchers intact. If the owner of this chassis would like this book it is here.

That a great find.
I would love one of those......
Would you possibly sell it if you have no takers?
