Matchbox 6b; Euclid 2 Axle Quarry Truck

As often happened in the first decade of Matchbox a similar, updated product replaced an existing one as 6b the Euclid Quarry Truck replaced 6a, the original Quarry Truck, remaining in the range from 1959 to 1963 when it was replaced by 6c, another updated quarry truck.

This one is always yellow, the wheels can be grey or black plastic and axles can be rounded or crimped. The black wheel version is fairly common and moderately priced, the grey wheels version though is rare and valuable.
