Ah, CDZ. Many happy memories!!
My dad was a good mate of Syd Marshal and I had many a fly over SYD area up front with "Uncle Syd".
AFAIK "Dick % Harry's" did some serious work on CDZ but were never paid, so she sat on the Milperra side near their workshops for a couple of years in the late 80s if I remember rightly. GDO really wanted her but too many $$$.
The DC2 that GDO had at The Oaks came from Harold Thomas' museum at Narellan and quite an adventurous night was had when we towed her to The Oaks!! A DC2 with no outer wings is still remarkably wide to tow along a public road.
Where is CDZ now, Steve, and how bad is she?
