This is a superb example of the Rare Hornby Dublo 4313 Gunpowder Van in Brown, running number B887002. Issued by Meccano, Liverpool between 1962 - 1969. With plastic wheels and couplings as standard. Why Rare? Many of these examples have been used by others on Wrenn chassis to denote a Rare Wrenn Wagon. Please note the grey Wrenn roof paint tends to be lighter and running numbers in-printed thicker in the body moulding on the Wrenn versions.  

Complete with original red/white striped box and packing rings.

Condition is "near mint" for its age.
