Dual Horse & Cart (page 517)
As (12) but with lime green horses.
Tinplate horse as in (7) to (12) but black with orange and white harness. Marx made horses with quite a range of colours for these clockwork carts.
Sparkling Climbing Tractor (page 517)
As (19) but friction-driven rather than clockwork.
Tricky Tommy Tractor (page 518)
As (22) and (23) but blue, and with black plastic wheels. These wheels usually indicate a Hong Kong version, and indeed the model has a small Hong Kong roundel next to the tool box on the right-hand side. Nevertheless, it is in an original Swansea box as (22), so Hong Kong models may have been sold in these boxes, and we have not yet seen a Hong Kong box.
