This is an excellent example of the Wrenn W.5086 "CO-OP" 6 Wheeled tanker in white, running number 172. THIS IS IN THE RARE P4 LONG BOX packaging not the single box example. Many examples of the white plastic have "browned" over the years this has NOT and is factory fresh. Meccano also suffered from the "browning" with their "UD" Tankers and Fish Van examples.

As with all P4 wagons this has metal rimmed wheels and pin wheel axles. 

Comes complete with P4 Long Box (type W7304), plastic insert and pacing pieces

Overall Condition is "near mint" for its age
