This is the Very Rare Wrenn W4655/A Mineral Wagon in Brown, with the difficult to find running number B54884. Only 260 were issued by Wrenn, Basildon from 1987, however as a collector over the years I believe this figure may be high. As with all Period 4 Wagons it has metal rimmed wheels. This also differs from  its grey mineral wagon counterpart (W4655) as it does not have a load.

Comes complete with P4 box (type W7304) and yellow plastic insert.

Overall Condition is "near mint"  for its age.
