This is a great example of the W2241 "Duchess of Hamilton" 4-6-2 Locomotive in LMS black. Running number 6229. This is one of the most popular of the Princess Coronation Class to collect and/or run with passenger traffic on any "OO Gauge" layout. Basildon produced this over Periods 3/4.    

This comes in a early Period 4 box (circa 1980/1), and includes packing rings, tissue,  and Instruction Manual.The bottom of the white inner box is stamped "Packer No 2" in red ink correct for this era.

My assessment of the Locomotive/tender is "near mint ",box is "excellent" considering their age.
