This is one of the early Maxitrak manufactured Aveling Porter tractors. It has recently undergone a full nut and bolt strip down, repaint and rebuild, and although complete and running would benefit from a little finishing off. It has been repainted during it's rebuild in a dark green livery rather than the original light green shown in the picture which was taken before the strip down started. The two dark green photos below are stock images to show what it should look like with a decent lining job.
More details and photographs to follow.
