Brian,
I assume you don't own this tool. It's very interesting, but also interesting is the array of frames in the background.
Who amonst us doesn't have a pushrod comb? (OK, David and Groily, maybe you guys don't.) However, I wonder if a 1955 comb looked any different.
When you think about it, the factory must have been chock full of production assembly jigs, which is what this looks like.
Now, my curiosity is really up. Do any of you folks live near the original Birmingham factory and are the buildings still there? If so, a tour of the basement of those, now probably, flats would be amazing.
