This is a great example of the W2230 Class 20 Bo Bo Diesel in BR Blue, with BR motif running number 8003.  This has the reliable Wrenn motor which does not tend to suffer from "stuttering" of some the earlier Hornby Dublo Class 20 Diesels. Has seen limited layout use in my opinion.

Comes in a Period 4 issued box , and includes tissue, packing rings, Hornby Dublo coupling conversion kit, and single page Instruction Sheet. The bottom box is not stamped which is not unusual for these early P4 factory issues.(Circa 1980/1) This was also when the Wrenn, Basildon factory tended to phase out the inclusion of the Hornby Dublo conversion kits. This however has been included.

Condition of Diesel/Box is "near mint" for their age.
