All working and velocities seem to work fine.
The brain has a small surface rust patch on the top and some of the edges where the paint has come off. It is also missing two of the knobs as in the photos.
It is numbered 000653, doesn't look like they made very many at all.
Please let me know if you are interested.
I live in Sheffield uk if anyone wants to have a look at it
All the best
Mike
