581 and 980 Horse Box Express Horse Van - U.S. market - 1952-60

At the MSMC meeting I saw this very rare box (with Van) for sale.Two things make this US version box even more rare than they already are:1. It has a yellow H Hudson Dobson Label (I have one with a green label see the Article on the Horse Boxes in the Dinky Articles). 2. The label at the end has been overstamped with the revised number 980, this has been observed on the 47 Traffic Signs and the Military Figures. Presumably done at Hudson Dobsons.
