BA, did you ever see one in person?
Kieth Bell recently mentioned that Allen felt it needed improvements, which might be why Allen did not describe it on his extensive website.
It wasn’t until late 80s that BigBros came out as a functional product, but I think the idea had been played around with by various tinkerers besides Allen prior. There might have also been some prototypes made in Europe, but not sure if later or earlier than Bryden.
Funny how Ewbank indicates it as a great Bryden invention, wondering if there might be some wry Aussie humor in his praise of the device (at least two mentions in Thrutch). |
