Arthur send a private message to Andrew Rowe on this forum about sprockets.
Andrew has previously advertised Australian pattern carrier sprockets for sale on this forum, but I do not know the current situation.
The Australian sprocket would be able to be used on a riveted carrier if one shoulder (they are on both sides of the sprocket) was to be machined (turned) off. The shoulder is about 3 or 4 ml. thick. Removing the shoulder would put the sprocket centre line back in the centre of the track.
Riveted carrier ones have no shoulders.
The pitch and mounting hole pattern are the same between the two types of carriers.
