Ka8 Fuselage Structure

Hi all,
Back in 1996 Schleicher issued a mandatory inspection requirement for the
metal structiure of the Ka8 fuselage. I have recently obtained a Ka8 which
unfortunately doesn't have log book. I am assured that all the inspections
and mods were carried out (the glider wwas previously owned by a large UK
Gliding Club) but there is no record of this. My question is what is the
cheapest way of doing this inspection, as an x-ray of the structure will be
in the region of GBP700.00
Thanks in advance
Pete H
