This is the much sought after Wrenn W2261/A "Queen Victorias Rifleman" Royal Scot Class Locomotive, in LMS Black, running number 6160. Introduced by Wrenn, Basildon in 1982 (Period 4), only 177 were produced over a limited 2 year period (1982/3). Any example of this Locomotive should appear in an early Period 4 box with the underneath of the inner box showing a 1982 or 1983 issue stamp.

This particular example is "Very Rare", as the top box has an "upside down" W2261/A ROYAL SCOT BLACK QUEEN VICTORIAS RIFLEMAN" stamp on one end, the other is correct.

This Locomotive I would put in the same class for RARETY as the the GREEN Royal Scot and the BLACK Caledonian.
