Saw these yesterday up on the opal fields
Are these carrier wheels or off something else ?
coulnt see any markings on rubber sections as they were too badly perished

The outside pictures are carrier wheels but the centre picture is too far away.

the trommells on the 3 mile camp used to have bren track around the outside with the wheels as pictured, around ten bren carriers had been cut up, some parts behind the shearing shed on the 7 mile. somewhere I,ve got some pics taken early 70,s.

While we are on the subject how about these. Photographed in the shed where carriers were built last year.
