Thanks to those list members who are using their knowledge and resources
to try to work out what this hub is. I realise now that this is proving
harder than I imagined, so I will give some further information which
may help. I have added 2 more photographs at
http://ntlworld.photobox.co.uk/album/1571123 . Having chalked the hub
barrel, it can now be seen reasonably clearly that this hub is marked J
Moyne. The threading on the axle is standard English and not metric.
The arrows on the pic No.4, which has the lockring removed, indicate
where the freewheel and axle turn, the two rings with pin holes in being
threaded together. The cone on the drive side is therefore within the
inner ring, and not visible from the outside. The hub was in a box
which contained mostly new Trivelox spare parts, but there is no
evidence that it is Trivelox related. The hub is for 36 spokes, but I
know insufficient about French parts to know if that is significant.
