I have just published a report with pictures of the Sibbertoft working event held weekend of 19/20 June and organised by The LINK Club.
Please go to the Chapter 2 landing page for details.
Chapter Two - Antique Caterpillar Machinery Owners Club (acmoc.org)

That looks great John and thanks for posting. It's easy for us State-side to forget that there are a lot of activities around the world. I really like that D2 scraper - any chance that there are some plans available for it? Mog (Martin) and I were lightly discussing the possibility of building a Cat "20" scraper - same design as a Cat 40 but sized for a D2. This scraper you showed is most of the way there. It would be great to see a video of it in action. Did the D2 have any trouble pulling it (what soil conditions?) and was any pushing attempted with it?
