Sturmey Archer K
In response to a request for K type changer details, this is a dismantled 1930's Sturmey Archer K Type quadrant changer.
Changer arm has worn out raised section (blob) that requires building up again in order to slot into the two selector holes (pictured) on the quadrant body when selected.
Sorry it's not a great photo, but in order to make the holes stand out, I've placed a piece of paper into the body.
Enlarge (lighten image, or stand on your head and look at your monitor from a different angle), if you need to analyse further.
