The W2203 "Shell" 0-6-0 Tank Locomotive was one in a range of "Private Owner"  Locomotives that Wrenn introduced in Period 3. The majority of production (just over 1300) were produced, with a very limited number in Period 4.The Locomotive looks superb with a rake of mineral wagons (W5051 with or without load) or W5040 range of 4 wheeled Petrol wagons,for freight operations on any "OO Gauge" layout. Sits equally on the layout or in the collection. This example is from the Period 3 Basildon build, circa 1975/6. 

The Locomotive comes complete in a Period 3 box, includes packing rings, tissue, Hornby Dublo coupling conversion kit, and Instruction Sheet. The underneath of the inner white box has the familiar sellotape residue marks denoting Period 3 issue.

Condition of the Locomotive/Box is "near mint", for their age.
