Thank you for having me! I've an old VHS tape of it and a dvd, I'll try sorting out the dvd on my laptop, I've got some pictures of the crane too, I'll try uploading them soon
That steam crane was named "Dick's Rig" after my grandfather named Richard(Dick) Barrett, I also have a 30 minute video of him and some of his colleagues talking about the steam crane and showing how it worked.
