I've acquired a DVD of the restoration of the FK96 n.A at Corinda, Brisbane. This is sold as a fund-raiser for the Sherwood/Indooroopilly RSL.
I have permission to on-sell the DVD to anyone interested. So If anyone's interested respond here so I can judge whether it's worth setting up the sale process. It will take me a week or so to get my act together to duplicate the DVDs and set up payment (probably Paypal). The likely cost is $A10 (7 Euro, $US9) + Postage (about $A4) - all net (of postage) funds will go back to the RSL.
