This is the W2206 R1 Tank Locomotive in BR Malachite Green, running number 31340.It has the late BR totem.Introduced in Period 1 it survived to the Period 4 Basildon era. Although it had a long production life, the quantities produced were far less than the W2205 version in BR Black and hence is becoming difficult to find in this "near mint" condition. As with all Wrenn R1 Loco,s it has a plastic body as opposed to metal (cast) which Wrenn used on its other range of steam Locomotives. Has seen minimal layout use in my opinion.

The Tank comes in a Period 3 box  and includes packing rings, tissue, Hornby Dublo Coupling conversion kit and  Instruction Sheet. The inner box has the normal sellotape residue marks correct for this period 3 era issue.(Circa 1974/5). 

Condition of the tank/box is "near mint", for their age.
