The Wrenn W2283 A4 Class "Woodcock" Locomotive was introduced by Wrenn in 1989 and production records indicate that only 173 of these models were produced, and hence they are very collectable.

 This is only one of 3 Grey Locomotives that Wrenn Basildon produced in Grey Livery, the others being;

• W2281 8F 2-8-0 War Dept Grey (running number 302)
• W2294 4-6-2 Duchess of Abercorn LMS Grey (running number 6234)
