Following on from the 960 Albion Cement/Concrete mixer, the very first issues of the 966 Marrel multi-bucket had a fault where the 'arms' flopped forward over the bucket and disconnected from the shaft. Meccano corrected this by putting a block on the casting ahead of the arms. The date in the box for Bruce is 11/60.
Opps no photos again. Will try another post.
